The old way (and only if using Axapta 3.0) is to use the Random class which is listed in the AOT under System Documentation\Classes. It will return a 15 bit integer only. See AX Daily.

But like Alex, I will prefer using the newer xGlobal::randomPositiveInt32().

dice = (xGlobal::randomPositiveInt32() mod 6) + 1;

is there a method to generate random negative numbers? – Tassisto Dec 04 '11 at 11:54

Sure: -xGlobal::randomPositiveInt32() Did you see the minus? – Jan B. Kjeldsen Dec 05 '11 at 11:22

Or: (xGlobal::randomPositiveInt32() mod 7) - 3, to generate -3 to +3. – Jan B. Kjeldsen Dec 05 '11 at 11:24

You can easily generate a positive int with this method, then just turn it into a real and divide after if you want decimals.

i = xGlobal::randomPositiveInt32();
