The impact of the number sas macro

[LineMoon]

Hello,

Please, what is the impact of the number of macros in application.

Best regards,

Nothing...

In terms of what, operation speed, program readability, how difficult it is to update/modify program

[LinusH]

The question is quite vague. Do you have a specific issue/requirement?

Usually, increasing the number of macros makes it more difficult to debug and maintain a program.  There are definitely exceptiions to the rule, for extremely well-written macros.  But in practice macros tend to add complexity.
