segmentation violation, bar code printing

[Frank Parker]

  Hi,
   
  I’ve recently been given the responsibility of maintaining our filePro data base and have a few questions I hope the members of this list can help me with.  
   
  Some background: SCO OSR 5.0.6  fp 5.0.09.  The filePro programs have been in use for over 20 years, being added to and modified by several people over the years.   Many years ago I programmed in fortran and cobol but have been away from it quite a while.
   
  The problem- We print a form from a record and when attempting to update the record after the form has printed, we get kicked out with a segmentation violation.  The processing that runs with the form updates several files as well as the file it’s run from.  This happens 95% of the time. Occasionally it will not create an error.  I know that permissions can cause this to happen and I have checked for that. I have also rebuilt all indexes in all affected files and that didn’t solve the problem. The processing table is what we used to call ‘spaghetti programming’ so I won’t inflict it on the list.   If I knew what other situations cause the segmentation violation I might have a better idea where to look.  
    Second problem- We print a form with a barcode on a Lexmark 2380, works fine but I would rather do it on a laser printer.  We have an HP4000n with the barcode font rom.  Printing the font list gives me the following escape sequence for code 3 of 9:   <esc>(0Y<esc>(s0p4.69h12.0v0s0b0T 
  I created a print code with this sequence substituting $1b for the <esc>'s and inserted this into the form just before the variable that contains the data (10 digit number) to be printed as a barcode.  Doesn’t work, obviously.  What am I missing?   To anticipate one answer, there is no budget for outside help. :)
  One additional question: is it possible to create a multidimensional array in filePro?  No immediate application, just curious.
Thanks for your time,
  Frank
