there are some working SQL that uses in-line C code.

They are pretty sharp.

Hi everyone
Before I forget, we are on V7r3

I know how to create an SQL function using procedures in service
programs and have done so many times My question is, Is there a way to
create an SQL function using C routines Without going into the "why
the %$^^ did you do it that way' explanation, we have a number of
fields that are numeric, but stored in alpha fields, where we have to
use the C routine QXXZTOI to convert it from alpha to numeric If the
numeric value is positive - then there is no problem in seeing what
the numeric value in the alpha field is However, if the numeric value
is negative - then a process I know as over punching (back from when
cards were used) is in effect For example The value '0001}" is really
-10 The value '0002J' is really -21

Now trying to use SQL against fields such as this becomes a no no
Hence my request

I have tried googling for the answer to this, but so far, nothing

As always, any and all answers welcome
