Nice summary, Daniel, very helpful. I'd forgot the details!

For the hexadecimally-challenged -

So one could take each byte into base 10 and separate them with periods 
- as your example has it -

0x0A56032A

0A = 10
56 = 86
03 = 3
2A = 42

Hence, 10.86.3.42

I believe I can envision a nifty little RPG subprocedure that could 
handle this, maybe use an array of uns(3)'s? - but the C version is 
there, so why bother?

*Regards*
