FUN 063
ATOH
ASCII to Hex conversion
Expression
Input − [ A ATOH (n) B ]− Output
Function
When the input is ON, the ASCII characters stored in n registers starting with A is converted into hexadecimal data and stored in B and after. The lower byte of source A is stored as uppermost digit of destination B, and followed in this order. The allowable ASCII character in the source table is “0” (H30) to “9” (H39) and “A” (H41) to “F” (H46). The allowablenger of n is 1 to 64.

Example
When R011 is ON, the ASCII characters stored in 8 words of D0300 to D0307 are converted into hexadecimal data, and stored in 4 words registers starting with RW040.

Note
•If index register (I, J or K) is used for the operand A, only n = 1 is allowed.
•If n is odd number, lower 2 digits of the last converted data will not be fixed, Use even for n.
