manipulating data in text file

[John Theune]

I’m looking into doing a new project.  I have some postscript files with a defined header in them.  I need to scan the header looking for the %%Start tag then count over 4 space delimited fields, read in a string and replace it with another string.  that’s all 🙂  I’ve started scanning thru the documention but can’t make much headway.  Has anyone done something like this and if so can they point me in the right direction.  I’m guessing that a tagged VRL can get me to the %%Start field then I would scan the next 125 bytes one character at a time to get the the field I want.  That seems rather ugly and I’m hoping someone else has gone down this path before.

Thanks,

John Theune

John,

You can do it all in tcl. I capture print files for processing into HL7 messages. Open the file and read it line by line checking for the string you want.

Send part of a sample file and I’ll see if any of my code is appropriate.
