Use of macros
| |||
| Home > Writing ARM Assembly Language > Use of macros | |||
A macro definition is a block of code enclosed between MACRO and MEND directives.
It defines a name that can be used instead of repeating the whole
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.
