Sure...that makes sense...thanks for walking me through it Charles.

Nope.

cvthc converts the raw bits into a hexadecimal string.

At that level, there's no difference between 4 bytes used to store a
character value and 4 bytes used to store an integer.

You want the hexadecimal value of an integer, so pass the integer.

Your prototype for cvthc can do one of two things:

//Useable for any type
d ConvertToHexString...
d pr extproc('cvthc')
d hexString * value
d bytes * value
d nbrBytes 10i 0 value

In which case you'd have
d string8 s 8a
d intValue s 10i 0
/free
ConvertToHexSting = (%addr(string8):%addr(intValue):%size(string8));
/end-free

or something like so:
d ConvertInt4ToHexString...
d pr extproc('cvthc')
d hexString 8a
d int4 10i 0 const
d nbrBytes 10i 0 value

d ConvertInt1ToHexString...
d pr extproc('cvthc')
d hexString 2a
d int1 3i 0 const
d nbrBytes 10i 0 value


d ConvertCharToHexString...
d pr extproc('cvthc')
d hexString 2a
d char 1a const
d nbrBytes 10i 0 value

// others?

The second option is easier to use, but you need to prototype cvthc
multiple ways.

HTH,
Charles

Use cvthc on the actual integer field.

Hmmm...I'm confused. I have a packed number (or zoned), and I move it
to
an
integer field (5U 0). I then take the %Char of the integer to get it
into
character format. Then I use cvthc to get the hex. However, when I
start
with the number 140, I get F1F4F0. I want 8C. If I use a DS overlay, I
get
what I want, but that doesn't seem to me to be the 'right' way.

D SomeDS ds qualified
D SomeChar 2A
D SomeInt 5U 0 overlay(SomeChar:1)

cvthc?

I think cvthc is the most straight forward way.
