SAS Macro Language: Reference

Interfaces with the Macro Facility

The DATA step, Screen Control Language, and the SQL procedure provide interfaces with the macro facility. Interfaces from the DATA Steps, Interfaces from Screen Control Language, and Interfaces from the SQL Procedure list the elements that interact with the SAS macro facility.

The DATA step provides elements that enable a program to interact with the macro facility during DATA step execution.

Interfaces from the DATA Steps
Element Description

EXECUTE routine resolves an argument and executes the resolved value at the next step boundary

RESOLVE function resolves the value of a text expression during DATA step execution

SYMGET function returns the value of a macro variable to the DATA step during DATA step execution.

SYMPUT routine assigns a value produced in a DATA step to a macro variable

***Interfaces from the DATA Steps***
Element	Description
EXECUTE routine	resolves an argument and executes the resolved value at the next step boundary
RESOLVE function	resolves the value of a text expression during DATA step execution
SYMGET function	returns the value of a macro variable to the DATA step during DATA step execution.
SYMPUT routine	assigns a value produced in a DATA step to a macro variable

Screen Control Language (SCL) provides two elements for using the SAS macro facility to define macros and macro variables for SCL programs.

Interfaces from Screen Control Language
Element Description

SYMGETN returns the value of a global macro variable as a numeric value

SYMPUTN assigns a numeric value to a global macro variable

***Interfaces from Screen Control Language***
Element	Description
SYMGETN	returns the value of a global macro variable as a numeric value
SYMPUTN	assigns a numeric value to a global macro variable

The SQL procedure provides a feature for creating and updating macro variables with values produced by the SQL procedure.

Interfaces from the SQL Procedure
Element Description

INTO assigns the result of a calculation or the value of a data column

***Interfaces from the SQL Procedure***
Element	Description
INTO	assigns the result of a calculation or the value of a data column
