Its main use is to create and update library files as ! 16: used by the loader. It can be used, though, for any similar ! 17: purpose. ! 18: ! 19: Key___ is one character from the set drtux_____, optionally conca- ! 20: tenated with v_. Afile_____ is the archive file. The names_____ are ! 21: constituent files in the archive file. The meanings of the ! 22: key___ characters are: ! 23: ! 24: d_ means delete the named files from the archive file. ! 25: ! 26: r_ means replace the named files in the archive file. If the ! 27: archive file does not exist, r_ will create it. If the named ! 28: files are not in the archive file, they are appended. ! 29: ! 30: t_ prints a table of contents of the archive file. If no ! 31: names are given, all files in the archive are tabled. If ! 32: names are given, only those files are tabled. ! 33: ! 34: u_ is similar to r_ except that only those files that have ! 35: been modified are replaced. If no names are given, all ! 36: files in the archive that have been modified will be re- ! 37: placed by the modified version. ! 38: ! 39: x_ will extract the named files. If no names are given, all ! 40: files in the archive are extracted. In neither case does x_ ! 41: alter the archive file. ! 42: ! 43: v_ means verbose. Under the verbose option, ar__ gives a ! 44: file-by-file description of the making of a new archive file ! 45: from the old archive and the constituent files. The follow- ! 46: ing abbreviations are used: ! 47: ! 48: c_ copy ! 49: a_ append ! 50: d_ delete ! 51: r_ replace ! 52: x_ extract ! 53: ! 54: FILES ! 55: /tmp/vtm? temporary ! 56: ! 57: SEE ALSO ! 58: ld(I), archive(V) ! 59: ! 60: ! 61: ! 62: ! 63: ! 64: ! 65: - 1 - ! 66: ! 67: ! 68: ! 69: AR(I) 3/15/72 AR(I) ! 70: ! 71: ! 72: BUGS ! 73: Option tv__ should be implemented as a table with more infor- ! 74: mation. ! 75: ! 76: There should be a way to specify the placement of a new file ! 77: in an archive. Currently, it is placed at the end. ! 78: ! 79: Since ar__ has not been rewritten to deal properly with the ! 80: new file system modes, extracted files have mode 666. ! 81: ! 82: ! 83: ! 84: ! 85: ! 86: ! 87: ! 88: ! 89: ! 90: ! 91: ! 92: ! 93: ! 94: ! 95: ! 96: ! 97: ! 98: ! 99: ! 100: ! 101: ! 102: ! 103: ! 104: ! 105: ! 106: ! 107: ! 108: ! 109: ! 110: ! 111: ! 112: ! 113: ! 114: ! 115: ! 116: ! 117: ! 118: ! 119: ! 120: ! 121: ! 122: ! 123: ! 124: ! 125: ! 126: ! 127: ! 128: ! 129: ! 130: ! 131: - 2 - ! 132: ! 133: ! 134: ! 135: AS(I) 1/15/73 AS(I) ! 136: ! 137: ! 138: ! 139: NAME ! 140: as - assembler ! 141: ! 142: SYNOPSIS ! 143: as__ [ - ] name ... ! 144: ! 145: DESCRIPTION ! 146: As__ assembles the concatenation of the named files.

If a file argument is provided, ! 213: the file is used for input before the console is read. Bas___ ! 214: accepts lines of the form: ! 215: ! 216: statement ! 217: integer statement ! 218: ! 219: Integer numbered statements (known as internal statements) ! 220: are stored for later execution. They are stored in sorted ! 221: ascending order. Non-numbered statements are immediately ! 222: executed. The result of an immediate expression statement ! 223: (that does not have `=' as its highest operator) is printed. ! 224: ! 225: Statements have the following syntax: ! 226: ! 227: expression ! 228: The expression is executed for its side effects (as- ! 229: signment or function call) or for printing as described ! 230: above. ! 231: ! 232: done____ ! 233: Return to system level. ! 234: ! 235: draw____ expression expression expression ! 236: A line is drawn on the Tektronix 611 display `/dev/vt0' ! 237: from the current display position to the XY co- ! 238: ordinates specified by the first two expressions. The ! 239: scale is zero to one in both X and Y directions. If ! 240: the third expression is zero, the line is invisible. ! 241: The current display position is set to the end point. ! 242: ! 243: display_______ list ! 244: The list of expressions and strings is concatenated and ! 245: displayed (i.e. printed) on the 611 starting at the ! 246: current display position. The current display position ! 247: is not changed. ! 248: ! 249: erase_____ ! 250: The 611 screen is erased. ! 251: ! 252: for___ name = expression expression statement ! 253: for___ name = expression expression ! 254: ... ! 255: next____ ! 256: The for___ statement repetitively executes a statement ! 257: (first form) or a group of statements (second form) ! 258: under control of a named variable. The variable takes ! 259: on the value of the first expression, then is incre- ! 260: mented by one on each loop, not to exceed the value of ! 261: ! 262: ! 263: - 1 - ! 264: ! 265: ! 266: ! 267: BAS(I) 1/15/73 BAS(I) ! 268: ! 269: ! 270: the second expression. ! 271: ! 272: goto____ expression ! 273: The expression is evaluated, truncated to an integer ! 274: and execution goes to the corresponding integer num- ! 275: bered statment. If executed from immediate mode, the ! 276: internal statements are compiled first. ! 277: ! 278: if__ expression statement ! 279: The statement is executed if the expression evaluates ! 280: to non-zero. ! 281: ! 282: list____ [expression [expression]] ! 283: is used to print out the stored internal statements. ! 284: If no arguments are given, all internal statements are ! 285: printed. If one argument is given, only that internal ! 286: statement is listed. If two arguments are given, all ! 287: internal statements inclusively between the arguments ! 288: are printed. ! 289: ! 290: print_____ list ! 291: The list of expressions and strings are concatenated ! 292: and printed. (A string is delimited by " characters.) ! 293: ! 294: return______ [expression] ! 295: The expression is evaluated and the result is passed ! 296: back as the value of a function call. If no expression ! 297: is given, zero is returned. ! 298: ! 299: run___ ! 300: The internal statements are compiled. The symbol table ! 301: is re-initialized. The random number generator is ! 302: reset. Control is passed to the lowest numbered inter- ! 303: nal statement. ! 304: ! 305: Expressions have the following syntax: ! 306: ! 307: name ! 308: A name is used to specify a variable. Names are com- ! 309: posed of a letter followed by letters and digits. The ! 310: first four characters of a name are significant. ! 311: ! 312: number ! 313: A number is used to represent a constant value. A ! 314: number is written in Fortran style, and contains di- ! 315: gits, an optional decimal point, and possibly a scale ! 316: factor consisting of an e followed by a possibly signed ! 317: exponent. ! 318: ! 319: ( expression ) ! 320: Parentheses are used to alter normal order of evalua- ! 321: tion. ! 322: ! 323: expression operator expression ! 324: Common functions of two arguments are abbreviated by ! 325: the two arguments separated by an operator denoting the ! 326: function. A complete list of operators is given below. ! 327: ! 328: ! 329: - 2 - ! 330: ! 331: ! 332: ! 333: BAS(I) 1/15/73 BAS(I) ! 334: ! 335: ! 336: expression ( [expression [ , expression] ... ] ) ! 337: Functions of an arbitrary number of arguments can be ! 338: called by an expression followed by the arguments in ! 339: parentheses separated by commas. The expression evalu- ! 340: ates to the line number of the entry of the function in ! 341: the internally stored statements. This causes the ! 342: internal statements to be compiled. If the expression ! 343: evaluates negative, a builtin function is called. The ! 344: list of builtin functions appears below. ! 345: ! 346: name [ expression [ , expression ] ... ] ! 347: Each expression is truncated to an integer and used as ! 348: a specifier for the name. The result is syntactically ! 349: identical to a name. a_[1_,2_] is the same as a_[1_][2_]. ! 350: The truncated expressions are restricted to values ! 351: between 0 and 32767. ! 352: ! 353: The following is the list of operators: ! 354: ! 355: = ! 356: = is the assignment operator. The left operand must be ! 357: a name or an array element. The result is the right ! 358: operand. Assignment binds right to left, all other ! 359: operators bind left to right. ! 360: ! 361: & ! 362: & (logical and) has result zero if either of its argu- ! 363: ments are zero. It has result one if both its argu- ! 364: ments are non-zero. (logical or) has result zero if ! 365: both of its arguments are zero. It has result one if ! 366: either of its arguments are non-zero. ! 367: ! 368: < <= > >= == <> ! 369: The relational operators (< less than, <= less than or ! 370: equal, > greater than, >= greater than or equal, == ! 371: equal to, <> not equal to) return one if their argu- ! 372: ments are in the specified relation. They return zero ! 373: otherwise. Relational operators at the same level ! 374: extend as follows: a>b>c is the same as a>b&b>c. ! 375: ! 376: + - ! 377: Add and subtract. ! 378: ! 379: * / ! 380: Multiply and divide. ! 381: ! 382: ^ ! 383: Exponentiation. ! 384: ! 385: The following is a list of builtin functions: ! 386: ! 387: arg___(i_) ! 388: is the value of the i -th actual parameter on the ! 389: current level of function call. ! 390: ! 391: exp___(x_) ! 392: is the exponential function of x. ! 393: ! 394: ! 395: - 3 - ! 396: ! 397: ! 398: ! 399: BAS(I) 1/15/73 BAS(I) ! 400: ! 401: ! 402: log___(x_) ! 403: is the natural logarithm of x. ! 404: ! 405: sin___(x_) ! 406: is the sine of x (radians). ! 407: ! 408: cos___(x_) ! 409: is the cosine of x (radians). ! 410: ! 411: atn___(x_) ! 412: is the arctangent of x . its value is between -(*p/2 ! 413: and (*p/2. ! 414: ! 415: rnd___( ) ! 416: is a uniformly distributed random number between zero ! 417: and one. ! 418: ! 419: expr____( ) ! 420: is the only form of program input.
