Operating mode

When the expression is not set to True:
  • in manual test mode, an assertion is displayed (equivalent to dbgAssert).
  • in runtime mode, an assertion is displayed if the assertions have been enabled (equivalent to dbgAssert).
dbgOnError allows you to automatically start a WLanguage procedure used to retrieve the comment linked to the error.
