*
* Generate pseudo-random real number in the range 0 <= X < 1.
*
* (single precision)
*
* !!! Microsoft Fortran dependent !!!
*
* Given (but used first time only):
* XSEED real an arbitrary real number
*
* The value returned is a pseudo-random number such that
* 0 <= sla_RANDOM < 1.
*
* Called: RANDOM (Microsoft run-time library)
