| Hello,
| 
| filePro v5.0.11D4 on OpenServer 5.0.6
| 
| I have a report that prints invoices to a file in ascii and then runs a 
| system call to convert the file to pdf format.  However, if I run a 
| lookup and getnext command prior to running the system call to create 
| the pdf file, the system call fails.  If I comment out the lookup and 
| getnext commands, the system call succeeds and the pdf is created.  Is 
| there are rule about using lookups in output processing? 
| 
| Below is the code with the lookup and getnext command.  It iterates 
| through each invoice line item and prints out the taxable items.
| 
| Thanks,
| Dave Burris

| ::getnext items; goto taxitem:

Which getnext do you comment out?  And I don't see your system call
here???

Your second 'not items' is always false, since you had to pass through the
first one first. :-)
