The only way that I know of may sound silly. Read the data and check. That is
basically what ISPF does. z/OS itself does not maintain any metainformation
about the existance of sequence numbers.
What I do, after I download ASM source or JCL or anything else which __might__
have sequence number in it to "mess me up", is unconditionally remove whatever
may be in columns 73-end_of_record, then remove trailing blanks too. It is
simple with Perl (I use Linux on my desktop, not Windows).
#!/usr/bin/perl
use strict;
use warnings;
while (<>) {
chomp;
s/^(.{1,72}).*$/$1/;
s/^(.*?) *$/$1/;
print $_,"\n";
}
Invoke with:
perl -i.bak ~/bin/noseq.pl list..of..files
The -i.bak saves the original by appending ".bak" to the original file name. If
you don't want a backup, just do -i and the file will be updated "inplace" with
no backup.
