Using symbolic feedback codes

Language Environment provides symbolic feedback codes representing the first 8 bytes of a 12-byte condition token. Using Language Environment symbolic feedback codes saves you from having to define an 8-byte condition token in your code whenever you want to check for the occurrence of a condition. Symbolic feedback codes are limited to testing for conditions rather than actual condition instances: no ISI information is tested using symbolic feedback codes because the comparison is only performed against the first 8 bytes of the condition token.

Language Environment provides include files (copy files) that define all Language Environment symbolic feedback codes. See Including symbolic feedback code files for information about Language Environment symbolic feedback code files.
