AHGzero Macro for Numeric Formatting

The `AHGzero` macro is designed to take a numeric value (`n`) and a desired length (`length`). It uses the SAS^© `%SYSFUNC(PUTN())` function to convert the number `n` into a character string. The `PUTN` function is used to apply a numeric format without explicitly specifying a SAS^© format, allowing SAS^© to choose a default format or use an implicit format to display the number at the requested length. This can be useful for adding leading zeros to a number if the specified length is greater than the number of digits in the number. The goal is often to ensure uniform presentation of numbers, for example, for identifiers requiring a fixed length.

Data Analysis

Type : CREATION_INTERNE

Data is passed directly as parameters to the macro and processed internally. No external data sources (files, databases) are used.

MACRO

Explanation :
This block defines the `AHGzero` macro which encapsulates the `%SYSFUNC(putn(&n,&length))` function. `%SYSFUNC` allows calling SAS data functions (like `PUTN`) within the macro processor environment. `PUTN(&n,&length)` converts the numeric value of the macro variable `n` into a text format of the length specified by `length`. This function is useful for character string formatting.
