Not sure precisely what you mean by this, but the LBCPYNV MI builtin can 
be used to copy a numeric field in one format to another without needing 
to know the sizes at compile time.

Not sure if that's really what you're trying to do, though?

You can use the Dynamic Screen Manager APIs to create fields on a screen 
where the sizes of the fields are only known at run-time.  You can then 
use LBCPYNV (as suggested above) to copy the field value from the screen 
buffer to a variable in your application.

So, the screen field size would be controlled by variables, and the field 
that you read it into in your program would be defined as the largest 
possible size for the field, to make it easier to work with.

Maybe?  I'm not exactly sure what you're trying to do.  Are you trying to 
remove a field from a record ("strip" it) so that the record now exists 
without the field?  Or are you trying to display a variable-length number 
on a screen?  or are you doing something with arrays?  (I didn't 
understand the "obviously an array process" at all... what on earth does 
this have to do with arrays?!)

Please clarify your situation, and I'll check to see if I have any code 
samples that are close.
