Procedure Naming Convention

Procedure names and label names should consist of meaningful mnemonics, connected by an underscore, and prefixed by a label group to indicate the relative hierarchy:

• High-level procedures should have a single-letter prefix, such as ‘A_’, ‘B_’.
• 2nd level procedures should have a two-letter prefix, such as ‘AB_’, ‘AC_’, ‘BA_’.
• 3rd level subroutines should have a three letter prefix, such as ‘ABA_’, ‘BBC_’.
• General-purpose procedures should have a two-letter prefix: ‘Z’ label, such as ‘ZH_’.
