Creating a Period to Follow Resolved Text

SAS now sees this statement:

DATA SALES1 SALES2;

Sometimes you need a period to follow the text resolved by the macro processor. For

example, a two-level data set name needs to include a period between the libref and data

set name.

When the character following a macro variable reference is a period, use two periods.

The first is the delimiter for the macro reference, and the second is part of the text.

set in&name..temp;

After macro variable resolution, SAS sees this statement:

SET INSALES.TEMP;

You can end any macro variable reference with a delimiter, but the delimiter is necessary

only if the characters that follow can be part of a SAS name. For example, both of these

TITLE statements are correct:

title "&name.--a report";

title "&name--a report";

They produce the following:

TITLE "sales--a report";

Displaying Macro Variable Values

The simplest way to display macro variable values is to use the %PUT statement, which

writes text to the SAS log. For example, the following statements write the following

result:

%let a=first;

%let b=macro variable;

%put &a ***&b***;

Here is the result:

first ***macro variable***

You can also use a “%PUT Statement” on page 332 to view available macro variables.

%PUT provides several options that enable you to view individual categories of macro

variables.

The system option SYMBOLGEN displays the resolution of macro variables. For this

example, assume that macro variables PROC and DSET have the values GPLOT and

Sasuser.Houses, respectively.

options symbolgen;

title "%upcase(&proc) of %upcase(&dset)";

The SYMBOLGEN option prints to the log:

SYMBOLGEN: Macro variable PROC resolves to gplot

SYMBOLGEN: Macro variable DSET resolves to sasuser.houses
