how to create a unix variable from the sas macro variable in unix shell script

hi All,

Hope you are all doing well. I need small help in creating the unix variable from the sas macro variable in unix shell script.

i have go through all the available articles and links available but i am not able to succeed with this.

Below is the code am using

this is my sas code named test.sas

options symbolgen mprint;

%let toto =123;
X 'export Lvalue=&toto';

%put &=toto;

above sas code is calling in the below unix shell script named test.sh

sas -sysin /{giving the path where the test.sas file is present}/test.sas -NOPRINT -nosyntaxcheck -noerrabend

echo $Lvalue

this is the result am getting while calling it.

sh -x test.sh
+ sas -sysin /{giving the path where the test.sas file is present}/test.sas -NOPRINT -nosyntaxcheck -noerrabend
/bin/bash: toto: command not found
+ echo

my expectation was Lvalue has to resolve to 123 but am achieving with the above code.

could you please help on this. Thanks in advance for your help on this.

SAS Macro variables do not resolve inside single quotes.

X 'export Lvalue=&toto';

uses single quotes.

Try

X "export Lvalue=&toto";

The environment variable you are setting is probably only going to live for as long as the shell that is running SAS lives. So trying to find its value after SAS has finished is not likely to work.
