.ds ZZ DEVELOPMENT PACKAGE
.TH JSTRING 3L "630 MTG"
.XE "jstring()"
.SH NAME
jstring \- draw character string on display
.SH SYNOPSIS
.B #include <dmd.h>
.sp
.B Point jstring (s)
.br
.B char \(**s;
.SH DESCRIPTION
The
.I jstring
function
draws, in the \s-1F_XOR\s+1 mode,
the null-terminated string
.I s
in the display Bitmap using mediumfont
so that the origin
of the rectangle enclosing the first character is at the current
window point.
It returns the current window point, which is left after the last character
of the string, so adjacent calls to 
.I jstring
can appear to concatenate their argument strings on the screen.
.SH EXAMPLE
The following program shows how \fIjstring\fR automatically updates
.IR PtCurrent .
.PP
.RS 3
.ft CM
.nf
#include <dmd.h>

Point jstring();

main()
{
    jmove (Pt(16,16));
    jstring ("I");
    jline (Pt(40,0), F_XOR);
    jstring ("love");
    jline (Pt(40,0), F_XOR);
    jstring ("my");
    jline (Pt(40,0), F_XOR);
    jstring ("630MTG");
