Hi Charles,

Thanks for the reply icon_smile.gif

The following is what i (thanks to the suppport from Robert and Vasanth) have running now:
Code:
DATA SEEDFILE;                                       
     INFILE SEEDFILE;                                 
     INPUT @014 SEEDVAL;                             
     SEED = INT(MOD (TIME(), SUBSTR(SEEDVAL,1)+0)) ; 
     RANVAL = INT(RANUNI(SEED)*SEEDVAL) + 1 ;         
     FILE RANOUT;                                     
     PUT ' RANDACT  ' RANVAL Z7. ; 

This does not use the "parm" but rather an input file and the random number is written to the RANOUT DD statement.
