Re: Code to move left justified alpha to numeric

Hi Art,

Parsing numeric values from character fields has been discussed
extensively on the RPG400-L list, also at Midrange.com.

The technique that I've used is to grab Barbara Morris' GetNum procedure,
make a few minor modifications, and place it in a service program so that
I can use it from any program on the system.  You might consider doing
the same thing.

Other options for character to numeric conversion have also been discussed
on RPG400-L.  MI functions, C functions, etc can all be called from
RPG IV.

Browsing through the archives, I found these messages which I have found
to be helpful:

For a more extensive discussion, here are some threads on the subject:

You can probably find even more info by searching the archives.   

Good luck,
