.FUNCTION....: #Random - Produce A Random Number
.CATEGORY....: functions
.DISCUSSION..:
#RANDOM returns a random number between a lowerbound number and an upperbound number.

More precisely, it returns a number X, where:

lowerbound <= X <= upperbound

That is:

if lowerbound is 3, and upperbound is 5, then #RANDOM will randomly return 3, 4, or 5.
if lowerbound is 999999997 and upperbound is 999999999, then #RANDOM will randomly return 999999997, 999999998, and 999999999.

RESTRICTIONS

The upperbound number is specified on the /A parm, and is required.
The lowerbound number is specified on the /B parm, and is optional. If omitted, it defaults to zero.
Both upperbound and lowerbound numbers must be integers
The lower bound cannot be less than zero.
The upper bound must be greater than the lower bound.
The upper bound cannot be greater than 999999999 (9 digits).
The difference between the lower bound and the upper bound cannot be more than 99999 (5 digits).

.EXAMPLE.....:

@echo off
:: a batch file to demonstrate generation of a
:: random number between 3 and 10, and putting
:: it into an environment variable named RAND

Fdate /f#random /A10 /B3 /p"@set RAND=">junk.bat
call junk.bat
del  junk.bat

echo Random number is %RAND%
:: use the RAND environment variable as you wish, here.

:: cleanup
set RAND=
