4.21 Use of macros

A macro definition is a block of code enclosed between MACRO and MEND directives. It defines a name that you can use as a convenient alternative to repeating the block of code.

The main uses for a macro are:

  • To make it easier to follow the logic of the source code by replacing a block of code with a single meaningful name.
  • To avoid repeating a block of code several times.
