i wanted to create one format but it gave error see like below
It looks like you have a very old version of SAS, where this syntax was not supported.
Run %put &sysvlong; and report here.
Doesn't the ANYALPHA() function return a numeric result? How is PROC FORMAT supposed to use that function to generate a character string? Make an INFORMAT instead.
236 proc format ; 237 invalue anyalpha other=[anyalpha()] ; NOTE: Informat ANYALPHA has been output. 238 run;
When the OP format is valid syntax it returns '0' or '1' for the formatted value.
Of course you can't do calculations with the result very well...
