I am not sure if Qbasic is able to do this, but here is what I need to do.
I would like to take a variable and break it in to pieces.
Example:
X = 325
I want to cut that up to make three more variables as follows
A = 3
B = 2
C = 5
I assume there is a way to do this using something similar to the LEFT$/RIGHT$ function, but I don?t know what that would be.
Any help would be greatly appreciated.
Thanks,
Jeff

You can convert numbers to string numbers with:
strnum$ = STR$(number%)
STR$ leaves the space on the left with positive values or the minus sign if negative. You can LTRIM$ positive values to get rid of the space.
IF you trim it first you can use:
A$ = LEFT$(strnum$, 1): B$ = MID$(strnum$, 2, 1): C$ = RIGHT$(strnum$, 1)
LEN can tell you how many digits the number is. It will count spaces too.
sign% = SGN(number) can tell the sign with 1 meaning positive and -1 as negative.
DON'T FORGET THAT A, B and C are STRING values that require $ or DIM A AS STRING
To convert strings back to numerical values use numberA% = VAL(A$)
strnum$ = STR$(number%)

Yes, you can use Integer division and MOD, remainder integer division.
number = 325
hundreds = number \ 100 ' = 3
tens = (number MOD 100) \ 10 ' = 25 \ 10 = 2
ones = number MOD 10 ' = 5
When MOD returns 0, the number is evenly divisible using integer division.
