Re: Converting an into to hex to char

[Vernon Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

Hi Gary

You don't convert the number to hex - you convert the hex value of 
either msgnbr or msgnbrchar to its hex nybbles - so the result is a 
4-character string - the first parameter of cvtch, right?

Can you show us your call to cvtch?

The 3rd parameter is the length of the 2nd parameter - so that should 
have a value of 2. It should be a 10i 0. First parameter is a 
4-character variable, 2nd parameter can be the 5i 0 integer or its 
2-character overlaid variable.

I know I'm stating the obvious. But sometimes a piercing glance at the 
obvious is what's needed.

Here's a prototype I have for cvtch - actually converts bytes to 
nybbles, once might say - these always get me a little turned around!

d convertCharacterToHex...
d                 pr                  extproc('cvtch')
d  toString                    512
d  fromString                  256
d  fromStringLength...
d                               10i 0 value
