Ah, so what you want to do is convert the integer value to a (hex)
byte. Just create a data structure with a 3-digit unsigned integer
(data type 'U') and an overlaid single character. Put your numeric
value into the int and read back the char.

I don't think that will work. The 3U value of 56 has the value x'38', not x'56'.

Here's one way to have the CHR$ procedure convert 56 to x'56':

D ds
D packed 3p 0
D firstByte 1a overlay(packed)

packed = num * 10; // if num = 56, packed = x'560f'
return firstByte; // x'56'
