sys.rand_string() returns a random string of length <len> from the characters <charset>.

Usage:

Arguments:

There are some examples of sys.rand_string() in the demo program dtf32.bld.1

Description:

sys.rand_string() is used to create a cryptographically strong random string from the characters in <charset>. It can be use to create random numbers by limiting <charset> to the digits you want to allow in the number and then converting the return to a number. For example, to create a random 5 digit number use:

     n = atoi(sys.rand_string("0123456789",5));
