Recently, I met the same problem, here is my solution:
%macro correct_sas_name(name);
%let flag=%sysfunc(notname(&name));
%do %until(&flag=0);
%let char=%substr(&name,&flag,1);
%let name=%sysfunc(TRANWRD(&name,&char,_));
%let flag=%sysfunc(notname(&name));
%end;
h_&name
%mend;
%let test=SAS#123!34;
%let correct_name=%correct_sas_name(&test);
%put &test;
%put &correct_name;
The LOG:
Have a look at the function nliteral : Converts a character string that you specify to a SAS name literal.
This is good way, thanks.
But, normally this way is not that common.
It's finally time to hack! Remember to visit the SAS Hacker's Hub regularly for news and updates.
