-; VerifyInput subroutine
-;
-; This subroutine will verify the user input is valid.
-;
-; Input: An address of a Null terminated string in register X.
-; Output: If valid Zero bit = 0 in CCR, if invalid, Zero bit = 1
-; and the string is outputed up to the error on the serial
-; console with an error message.
-; Registers in use: X for the address of the string, A for reading characters.
-; Y to count the number of digits in a number, & B to count the number of numbers
-; Memory locations in use: Memory Address for serial line, address of the string, 1 byte for operator
-;
-; Comments: This subroutine will modify the user string if invalid.
