Re: Converting Decimal to Hex

Hello, Michael:

All data in the machine is stored in bytes (or characters) in memory (in main storage or on disk).

A byte contains 8 bits, capable of representing values from 0 to 255 (decimal).

Each byte (or character) is represented by two hexadecimal digits.

A 32-bit integer (10i 0 in RPG IV) occupies 4 bytes.

A 64-bit integer (20i 0 in RPG IV) occupies 8 bytes.

The cvthc MI instruction operates on bytes, converting each byte to a 2-character "hex" character representation (suitable for viewing or printing).

HTH,

Mark

Convert Hex to Character (CVTHC)

*Operand 1*: Character variable scalar.

The variables aren't really char? Do you have a prototype that shows how to
pass an integer to cvthc?

Thanks...

That's where you go wrong. By using %Char you created the character
_representation_ of the value. If you want the hex version of the int
then simply pass the int or do it using a DS or some other form of
redefinition make it available as character without any transform.
