Re: Same field names in different files

This was referring to a maintenance programmer going in at a later date 
and trying to use the larger of the two fields without first checking 
things out.  But nevermind.

Re: Same field names in different files






We are not talking about this.
Off Course you will end up with your 5 XXXX in BIGNAME when you do this.
But why should you define these things in a datastructure and think that 
when you do a EVAL *ALL to  SMALLNAME that it would affect all of the 
positions in BIGNAME??
Off Course MOVE(P) against SMALLNAME makes then no difference!!
But that makes it hypothetical and not something from real life (I can not 
think of any reason to define and handle it in that way).
 
So when we talk about a real situation where I have a BIGNAME with *ALL(X) 
and a separate SMALLNAME with *ALL(Y) and I want the value of SMALLNAME in 
BIGNAME; I can do:
MOVE(P) SMALLNAME BIGNAME.
As a result BIGNAME will have the value of SMALLNAME with 5 leading blanks 
(If character fields).
MOVEL(P) SMALLNAME BIGNAME.
As a result BIGNAME will have the value of SMALLNAME with 5 trailing 
blanks (If character fields).
 
When you want it anyway in a datastructure you will have to do manaullay 
what the (P) part of the MOVE can do for you, say:
CLEAR BIGNAME
EVAL *ALL(Y) SMALLNAME
Or perhaps if you want that BIGNAMES contains *ALL(Y):
EVAL *ALL(Y) BIGNAME is your solution?????
 
Cheers,
Eduard

I posted a previous reply to this that even MOVE(P) would fail under.

How so?
If they are defined in a data structure as
d ds 
d BigName 40 
d SmallName 35 overlay(BigName)

If you use BigName to get SmallName all the time you are fine. But let's 
say BigName contains 40 characters all 'X', and we do
Eval SmallName = *All('Y')

BigName would have 35 Y's and 5 X's at end nes pas?

Just change the eval to
MOVE(P) *ALL('Y') SmallName

End result would be the same.

So then you use MOVE(P) to padout the not covered part of the to field.

The only problem with that I see is that if a future programmer tries to
use the longer of the two fields (for example, use the shorter field as
input to populate the longer field) then you could end up with data in the
last 5 chars that is left over from a previous operation.

Re: Same field names in different files






I agree with the responses that say a different size means you need a
different field name.

My solution to this is to set up the shorter field as an overlaid field
(or DS if you prefer) based on the field in the database. That way, it's
automatically populated with the correct data.
