RE: DDS screen: how to ensure field keyed is numeric for alpha-descri bed field

["Richard Jackson" <richardjackson@xxxxxxxxxxxxxxxxxx>]

I never cry in admiration, I'm too busy duplicating the idea.

Imagine divides by 10 in a loop to move the decimal place to the left and
multiplies by 10 in a loop to move it to the right.

There are at least three ways to improve this technique that have been
available for more than 10 years.  (1) Move numeric to character then
character to numeric.  (2) There exists a MI instruction that shifts the
decimal.  (3) We could also do it with data pointers - if anyone remembers
them.

Before ILE, calling an external MI program to do this is too expensive.  I
tried to get the IBM Toronto people to give us a built-in RPG language
function.  There is also instruction "copy external form to numeric" to
convert character values to numeric values that could have been used instead
of the RPG numeric scrub that I mentioned.  No deal.  And I couldn't get JDE
to convert their code to ILE so there it sits.

Hi Richard,

Don't leave us in suspense! Tears of admiration or disgust? What's the
trick?
