Hi Arnaldo,

Try this:

INPUT PROGRAM. - string rancode (a15). - LOOP #I = 1 TO 40000. - loop #j = 1 to 15. - compute substr(rancode,#j,1) = substr('ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789',trunc(uniform(36))+1,1). - end loop. - END CASE. - END LOOP. - END FILE. END INPUT PROGRAM. EXE.

Greetings

Jan

I mean one variable and 40000 cases

I mean random numbers they can't be repeated (they have to appear one time each).

> And, the word 'alphanumeric' in a sentence with the words >'random numbers' is also confusing.

read figures, digits, numerals they are composed by some letters and numbers, appearing in random order

Yes, I prefer they are not case sensitive 'AEIOE42DD89DUYW' = 'AeIOE42dD89DUYW'

Thanks a lot. Arnaldo.
