: //usr/bin/asa complies with standards, which is hunky-dory, and what
: it does is pretty clear from its man page, but I cannot imagine what
: kind of files would have been prepared with those initial space, 0,
: 1 or + on each line. (space turns out to mean whitespace, BTW.)
: IOW, I'm looking at an answer for which I can't perceive the question.
I don't have my SCO system available for "man asa," but the file format
sounds like Fortran carriage-control for line printers....
space advance 1 line before printing (normal)
1 advance to top-of-form before printing
+ no advance before printing
0 advance two lines before printing
I have to admit I'm not too sure about the "0"; it's been a long, long,
time. ... rb
