AHGsome Utility Macro

This macro, '%AHGsome', accepts a single parameter, 'str', which is intended to be a character string. Its purpose is to return a logical expression that evaluates to true if 'str' contains text (is not blank/empty) and false otherwise. To do this, it delegates the check for string emptiness to another macro, '%AHGblank', and then inverts the result of this check (not %AHGblank(&str)). This approach is typical for utility macros designed to simplify logical conditions in other SAS^© programs.

Data Analysis

Type : INTERNAL_CREATION

The '%AHGsome' macro does not process external or internal SAS datasets. It operates solely on a character string provided as a parameter during its call, performing a check for its non-emptiness. The 'data' are therefore character string inputs passed directly to the macro.

MACRO

Explanation :
This block defines the '%AHGsome' macro. It takes an argument named 'str'. The instruction 'not %AHGblank(&str)' indicates that the macro returns the negation of the result of '%AHGblank(&str)'. If '%AHGblank' evaluates to true for an empty string, then '%AHGsome' evaluates to true for a non-empty string.
