Doug, CEERAN0 returns a floating point value between 0 and 1. So to get a number between 1 and 1000, simply multiple the value returned by CEERAN0 by 1000 HTH, Charles -----Original Message----- From: rpg400-l-bounces@xxxxxxxxxxxx [mailto:rpg400-l-bounces@xxxxxxxxxxxx] On Behalf Of Douglas Palme Sent: Friday, March 16, 2007 10:41 AM To: 'RPG programming on the AS400 / iSeries' Subject: Random Numbers I have been looking for a random number generator for RPG and found an example on IBM's website. I know that with other languages I can specify that I want the random numbers that are generated to fall within a specified range, IE: between 1 and 1000. Here is the code that IBM suggested: Fseedpf uf e disk usropn F Frandpf o e disk usropn F DTimes c const(1000) Dfactor c const(10000000000) D Dstdpacked s 15p 5 Dstdint s 10i 0 Dstddouble s 8f Dstdfc s 12a D Drandnum_gen pr extproc('CEERAN0') Dpr_seed LIKE(stdint) Dpr_randum like(stddouble) Dpr_fc like(stdfc) D Dcounter s like(stdint) D Dseednum s like(stdint) D Drandnum s like(stddouble) Dfeedbackcode s like(stdfc) D C open seedpf C open randpf C C read seedrec C eval seednum = %rem(seedfld:factor) C for counter = 1 by 1 to times C callp randnum_gen(seednum:randnum:feedbackcode) C eval randfld = randnum C write randrec C endfor C eval seedfld = seednum C update seedrec C close randpf C close seedpf C eval *inlr = *on Maybe I am blinding myself here, but with using the C API, I do not see any way of setting a range. Has anyone else performed such an operation before? If so, how did you specify the lower and upper range? **************************************************************************** This transmission may contain information that is privileged, Confidential and/or exempt from disclosure under applicable law.
