Subject:      Re: SAS INFILEing a perl program using a PIPE

Kevin -
  As the FILE and the INFILE do not look related from reading your SAS code
why not try placing the INFILE statement before the FILE statement. Perhaps
this will make SAS less confused?

  But I am not sure what purpose your FILE/PUT statements are doing?  Are
you trying to pass the filename in the PUT statement to the actual PERL
program?  If so they why not just pipe it into the PERL program?

If you want to pipe in the content of the file then use:
  filename abi_seq pipe "perl c:\perl\program\abi_seq.ps < c:\a19.ab1";

If you want to pipe in just the filename then use:
  filename abi_seq pipe "echo c:\a19.ab1 | perl c:\perl\program\abi_seq.ps";
