Alias Statement

Format
alias aliased_name : original_name;
Description
The alias statement allows for the creation of new names to alias, or to provide an alternative reference to, names in a program. This can be used to shorten, or lengthen, variable names, or to match names in a dictionary with preexisting code using a certain naming convention.
Example 1: Shortening Dictionary Names to Quicken the Typing of Variables
alias   P14 : P14_AGE,
        P15 : P15_RELATIONSHIP,
        P16 : P16_SEX;
Example 2: Using Aliases to Standardize Variable Names so that Logic Can be Reused Across Programs
alias   AGE             : P14_AGE,
        RELATIONSHIP    : P15_RELATIONSHIP,
        SEX             : P16_SEX;
In both examples, P14_AGE, P15_RELATIONSHIP, and P16_SEX are the names of items declared in a dictionary. Once the alias statement has been specified (in PROC GLOBAL), the names P14 and P14_AGE can be used interchangeably. For example, these two statements are identical:
if P14_AGE < 18 and P16_SEX = 2 then

if AGE < 18 and SEX = 2 then
