3: .SH NAME
4: bscpr \- BISYNC Batch File Print Utility
5: .SH SYNOPSIS
6: bscpr [-ascii] [-page=pp] [chan=lineno ...] [file]
7: .SH DESCRIPTION
8: .P
9: The
10: .I bscpr
11: utility is used to paginate a file which
12: contains IBM 2780 or 3780 terminal control characters and escape sequences.
13: These terminals have line printers which utilize a paper tape loop
14: and holes punched in certain locations to control paper motion. The
15: loop of paper tape contains twelve channels; an escape code is used
16: to tell the printer to skip to a position on the page corresponding
17: to a hole in a certain "channel". Usually, channel 1 corresponds
18: to the top of the form, channel 12 to the bottom, and the remainder
19: correspond to the vertical equivalent of horizontal tab stops in
20: that they represent a physical line number on a page.
21: .P
22: The
23: .I -ascii
24: parameter specifies that the escape
25: sequences used for printer positioning were of the ASCII style; the
26: default is the EBCDIC style (differences are slight, see the table below).
27: The
28: .I -page=pp
29: parameter is used to specify the page length to be used.
30: The
31: .I chan=lineno
32: parameters give the correspondence of channel numbers to line numbers on a page.
33: The page length defaults to 66 lines, and channel 1 always corresponds to
34: line 1; skipping to unspecified channels results in no action.
35: .P
36: The following table shows the escape sequences which may appear at
37: the beginning of a line to control paper positioning. If there is
38: not an escape sequence at the beginning of a line, single spacing
39: is automatically selected for that line.

70: .P
71: .I Bscpr
72: keeps track of the current line number as
73: it displays the lines of the received file.
74: Normally, each line is terminated with the necessary number of newlines
75: (one for single spacing, two for double, three for triple,
76: and the difference between
77: the current line and line corresponding to a specific channel in
78: a skip to channel operation).
79: Space suppress results in a line terminated via a carriage return,
80: and the current line number is not incremented.
81: Any attempt to move past the bottom of the page via spacing or skipping
82: will result in a carriage return and form feed (ASCII FF).
83: An attempt via skipping
84: to a channel to position to a line number less than the current line
85: number will result in a form feed, then line feeds to get to the
86: proper line on the new page.

98: .SH DIAGNOSTICS
99: .P
100: bscpr: unrecognized option (<flag>)
101: .IP
102: The option <flag> is not a valid parameter as shown in the synopsis.
103: .P
104: bscpr: not a numeric (<parameter>)
105: .IP
106: The number of lines for the
107: .I -page
108: parameter or the channel or line number for the
109: .I chan=lineno
110: parameter is not a numeric.
111: .P
112: bscpr: channel number not 2 to 12 (<parameter>)
113: .IP
114: The channel number given is not in the range 2 to 12, inclusive.
115: There are only escape sequences for channels in this range, not counting
116: the channel 1 specification, which is always set to line 1.
117: .P
118: bscpr: line assignment for channel <chan> is greater than page length
119: .IP
120: Channel assignments for line numbers must be between line 1 and the
121: last line on the page (given by
122: .I -page
123: or defaults to 66).
124: .P
125: bscpr: <file> not found
126: .IP
127: The file name parameter <file> could not be opened for reading.
128: Either it does not exist, or the mode does not permit reading.
