String to Numeric

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

I have a field I am allowing my users to put in a string value
(container number, in the format XXXX999999) or a numeric
value (invoice number, 999999).  I now have this variable that
contains one or the other, but in either case, it is left justified.

So I either have:
'ABCD123456 '
or
'1234       '

Now I'm kinda stumped.  I can figure out if it is numeric or a
container number by using the Check opcode.  But, once I
know it's numeric, just how do I convert this thing to a numeric
value?

I tried a Data Structure, but no success.   To map successfully,
I think the value would have to be like:
'00000001234' and I'm not really sure how to get it there.  I know
we have the DIGITS function in Query, but it doesn't work in RPG,
and is going the wrong way anyway.

Anyone have any ideas?

I think I'm going to wind up building a string like '000000000000001234'
using
'00000000000' + %TRIM(InputVal) and SUBSTRing it.
