>>You mean a CHAR, right?
NOPE. although he says char in his post his code is about NUMS.
The following is for his info...
An int is 1byte long 00000000 or 8 bits, each bit can hold 1 of 2 values, either a 1 or 0.
2^8 or 2 to the 8th power is 256, that's the max an int or value that's 1byte long can hold. A signed INT, which is the defualt for INT and other number vars, takes 1bit as the sign for negative values so it's 2^7 = 128 positive and -127 negative 0 is counted as a positive value.
So an INT is... 1byte
INT -127 to 128
unsigned INT 0 to 255 only positive values (256 total values counting 0)
A LONG is....2bytes
LONG -32,767 to 32,768
unsigned LONG 0 to 65,535
