Pre/Post Variables

The following tables list all pre/post variables for setting up pre- and post-processing.

Pre/post variable considerations:

  • Pre/post variables are case-sensitive.
  • Pre/post variables that can be arbitrarily long (values marked with * below) are truncated by prepost scripts.
