LST Program Structure
Identification of Main Program in LST
From the LST file the main program is identified with the set of text that starts with ‘HP’ and ends with M30.
Identification of Sub programs in LST
In the LST file, the sub programs are called from the main program with the syntax “SP@”, where @ is the number of sub program, eg: SP1 will call the respective sub program!
