Add a $var_def command
Inputs: Parm1 = UJP pathname
Parm2 = Variable name and value to add
Returns: 0 = success
-1 = cannot lock UJP
-2 = cannot open UJP
-3 = cannot read UJP
-4 = cannot write UJP
-5 = UJP is an active job instance
Before processing this function, any $fs_template $var_def commands are converted to normal $var_def commands. The use of $fs_template for $var_def commands is deprecated (but continues to be supported).
The string in Parm2 should consist of a variable name, then white space, then the variable value. The name should not contain embedded blanks. If the value contains embedded blanks, it should be surrounded by double-quotes and any embedded double-quote characters should then be duplicated.
The variable BROADCAST_TYPE should not be set using this function. Use the SetBroadcastType function instead.
This function adds the generated command line to the UJP. If there are existing $var_def commands in the file, the new command is added after the last such command. If not, the command is added at the start of the file.
To delete a variable, use the DeleteCommands function.
Note that defining variables with names of the form BCFn in a UJP file serves the special purpose of selecting records for launch. For more information see $var_def.
Add or override an existing variable:
strcopy(parm2, "MY_VARIABLE \"New Value\"");
res = JobDllEntry("AddVariable", parm1, parm2, 0);
