This function deletes all instances of $var_def commands in the UJP.  It is not an error if no such commands are present.

The function also deletes all instances of $fs_template $var_def commands.

To delete a specific named variable, you can either use the AddVariable function to give it an empty value, or use the DeleteCommands function.

Example:

strcopy(parm1, "@FFJOBS\\00001234\\00000123\\JOBTYPE.UJP");

res = JobDllEntry("DeleteAllVariables", parm1, parm2, 0);
