Chapter 3
Macros
After you have gone to the trouble of creating (and debugging) a PRESCRIBE command
sequence, it is inefficient to use it only once, but it is a nuisance to type the same
sequence repeatedly. The solution is to make the sequence into a macro. Then you can
execute the entire sequence with a single CALL command. The procedure for defining a
macro command sequence is simple.
Step 1:Assign a name to the sequence. Place the name at the top of the sequence (ending
with a semicolon).
Step 2:Add the PRESCRIBE command MCRO in front of the name.
Step 3:Add the PRESCRIBE command ENDM at the end of the sequence.
