What are Symget and Symput?

What are Symget and Symput?

SYMGET returns values of macro variables during program execution, whereas the SYMPUT function assigns values that are produced by a program to macro variables during program execution. SYMGET resolves only a single macro variable.

What is the difference between call Symput and call Symputx?

Re: CALL SYMPUT vs CALL SYMPUTX Both SYMPUT and SYMPUTX convert the value to character before assigning to a macro variable. SYMPUT gives you a message on the log about the conversion, while SYMPUTX does not. SYMPUTX takes the additional step of removing any leading blanks that were caused by the conversion.

What is a macro variable in SAS?

A macro variable in SAS is a string variable that allows you to dynamically modify the text in a SAS program through symbolic substitution. The following example demonstrates how to create and use a macro variable. First we set up some system options to have a more concise output style.

What are macro functions in SAS?

Function Description
\%LENGTH Returns the length of a string.

What is call Symputx in SAS?

CALL SYMPUT and CALL SYMPUTX in SAS are the most commonly used DATA Step call routines to interact with the Macro Facility in SAS. Both are used to assign a value of DATA step to a macro variable. SYNTAX: CALL SYMPUT(macro-variable, value);

What is _N_ in SAS?

Each time the DATA step loops past the DATA statement, the variable _N_ increments by 1. The value of _N_ represents the number of times the DATA step has iterated. You can use the value of this variable to help locate errors in data records and to print an error message to the SAS log .

When we can use call Symputx and why?

CALL SYMPUT uses a field width of up to 12 characters. CALL SYMPUTX left-justifies both arguments and trims trailing blanks. CALL SYMPUT does not left-justify the arguments, and trims trailing blanks from the first argument only. Leading blanks in the value of name cause an error.

What is Symputx in SAS?

Assigns a value to a macro variable, and removes both leading and trailing blanks. Using the SYMPUTX function does not modify the values of the macro variable in the SAS client. …

What is Symput function in SAS?

CALL SYMPUT is a SAS® language routine that assigns a value produced in a DATA step to a macro variable. It is one of the DATA step interface tools that provides a dynamic link for communication between the SAS language and the macro facility.

What are macro variables?

Macro variables are tools that enable you to dynamically modify the text in a SAS program through symbolic substitution. You can assign large or small amounts of text to macro variables, and after that, you can use that text by simply referencing the variable that contains it.

What does \%include do in SAS?

The \%INCLUDE statement executes statements immediately. The INCLUDE command brings the included lines into the SAS Studio Code tab but does not execute them. You must issue the SUBMIT command to execute those lines.

How does PDV work in SAS?

SAS uses the input pointer to read data from the input buffer to the PDV. At the moment, the input pointer is positioned at the beginning of the input buffer. Next, the INPUT statement reads data values from the record in the input buffer according to instructions from the INPUT statement and writes them to the PDV.

What is the difference between symget and symut in SAS?

1 SYMGET returns values of macro variables during program execution, whereas the SYMPUT function assigns values that are produced by a program to macro variables during program execution. 2 SYMGET accepts fewer types of arguments than the RESOLVE function. 3 SYMGET is available in all SAS programs, but SYMGETN is available only in SCL programs.

What is the use of call symput and call symputx in SAS?

CALL SYMPUT and CALL SYMPUTX CALL SYMPUT and CALL SYMPUTX in SAS are the most commonly used DATA Step call routines to interact with the Macro Facility in SAS. Both are used to assign a value of the DATA step to a macro variable. In this article, we will demonstrate some of the uses and important facts of these two call Routines.

What is the difference between symget and call symput?

You use CALL SYMPUT (or better CALL SYMPUTX as it is more flexible) to create macro variables from data step values. You use SYMGET to get macro variable values. Usually you can just reference the macro variable instead. Here are some situations where you would want to use SYMGET.

Why use the symput routine and symget function?

Because one of the most powerful incentives to use the SAS® macro language is to allow SAS programs to be more data-driven, it is critical for the DATA step and the macro facility to “talk” to each other. The SYMPUT routine and the SYMGET function provide two mechanisms to facilitate this communication.
