quoting each value in a macro variable

Saravanan — Thu, 06 Feb 2014 20:32:09 GMT

Hi All,

is it possible to quote each values in a macro variable separately?

For example, I have a macro variable %let test = a b c;

I would like to use the test macro variable values in a character array for initialization. Character array needs a quoted value for initialization. is it possible to use the test macro variable values in a character array initialization and quote individual values to satisfy character array requirements?

I would like to have something like this: array sample(3) $ 2 (&test.); in this piece of code the test macro variable is not quoted for individual values so it throws an error.

Thanks in advance for your help.

%let x=a b c;

%let y=%str(%')%qsysfunc(tranwrd(&x,%str( ),' '))%str(%') ;

%put x=&x y=&y ;

x=a b c y='a' 'b' 'c'

Thank you for your reply. It seems to quote the values. But when i use it in array it throws an error.

for example:from your above macro example, array test(3) $2 (&y.); This piece of code throws an error.

Try

%let y=%UNQUOTE(%str(%')%qsysfunc(tranwrd(&x,%str( ),' '))%str(%')) ;
