When parsing a large input text stream, UnForm can run out of memory and report an error 33.  This is generally due to the default construction of an internal text array of all lines of the job, called textall$[all].  This array is created to enable code blocks to easily work with all job text, but this is rarely used in practice.

 

To turn off creation of this array, there are two techniques:

 

  1. Add -notextjob to the uf80c command line to turn it off job by job
  2. Set textjob=0 in uf80d.ini to turn off  for all jobs
