Macro Body Structure

The macro body is defined in the same way as a sub-program.

Format: Oxxx

O identifies it as a macro.

xxx is the label number.

Example 1:	N200	O 201
	N210	-----

Terminate the macro with an M99 code.

Use local variables within the body of a macro or sub-program only. You cannot use them to transfer data to other macros or sub-programs. If further sub-program calls are made from the macro body, you must transfer data from the local variables to common variables. The common variables can then be referenced to transport data to the further sub-program.

N220 #100 = #20

N230

Common variables range from #100 to #220.

The macro must either be part of the program from which it is called or "included" using the program inclusion code. Refer to "File Inclusion" in this section.
