What does call Symputx do in SAS?

Assigns a value to a macro variable, and removes both leading and trailing blanks.

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 the difference between Symput and 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 the use of Sysfunc in SAS?

\%SYSFUNC allows us to convert a macro variable using a format without having to resort to a data step. This example converts a macro variable date string into a macro variable containing the SAS date representation using an existing SAS format.

What is Symbolgen in SAS?

The SYMBOLGEN system option tells you what each macro variable resolves to by writing messages to the SAS log. This option is especially useful in spotting quoting problems, where the macro variable resolves to something other than what you intended because of a special character.

What is Symget in SAS?

Details. SYMGET returns a character value that is the maximum length of a DATA step character variable. A returned value that is longer is truncated. If SYMGET cannot locate the macro variable identified as the argument, it returns a missing value, and the program issues a message for an invalid argument to a function.

What is PUTN function in SAS?

Enables you to specify a numeric format at run time.

What is Tranwrd SAS?

Details. The TRANWRD function replaces or removes all occurrences of a given word (or a pattern of characters) within a character string. The TRANWRD function does not remove trailing blanks in the target string and the replacement string. The value that the TRANWRD function returns has a default length of 200.

What is _error_ in SAS?

Details. The ERROR statement sets the automatic variable _ERROR_ to 1. Writing a message that you specify to the SAS log is optional. When _ERROR_ = 1, SAS writes the data lines that correspond to the current observation in the SAS log.

What does Mlogic do in SAS?

causes the macro processor to trace its execution and to write the trace information to the SAS log. This option is a useful debugging tool.

What is the use of call symput 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 DATA step to a macro variable.

What is the use of symputx?

Here the call symputx comes into rescue. It can help us assigning the macro variable without the extra note in the log. It also strips the leading and trailing blanks. It also helps us to choose the scope of the macro variable (local or global).

What is the difference between call symput and callcallsymputx?

CALL SYMPUT, however, writes a note to the log stating that numeric values were converted to character values. CALL SYMPUTX uses a field width of up to 32 characters when it converts a numeric second argument to a character value. CALL SYMPUT uses a field width of up to 12 characters.

Does call symputx automatically convert the value assigned to macro variable?

Does CALL SYMPUTX automatically convert the value assigned to the macro variable to character (assuming it is numeric) or is the numeric format preserved? 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.
