AHGhashvalue Macro - Hash Value Retrieval

This utility macro simulates an associative array (hash) using macro variables. It takes a hash identifier and a key (handle), determines the key's index via the external macro %AHGindex, then dynamically constructs the name of the variable containing the value to return it.

Data Analysis

Type : CREATION_INTERNE

The processing relies exclusively on the manipulation of macro variables and parameters provided at call time. No SAS data table is read or written.

MACRO

Explanation :
