Re: Likerec usage

But in this case records match, only different LF's sharing the same record
format.

I guess there are other reasons besides the name.

Thanks anyway, I'll ask IBM.

The record format name pointed to by the data structure must match the
record format name of the File used on the input operation.

RPG just doesn't allow you to substitute a "similar" data structure for
input operations like this on Externally Defined files.
It must be an exact match when trying to use a Result Data Structure.


This is probably a requirement to protect programmers who don't realize
the repercussions of using a Result data structure.

RPG does not perform type checking when a result data structure is used.
It just moves the data across.
Which means the error (data decimal or the Date, etc.) would be sent later
when the field is used.


That's also one reason I prefer to use EVAL-CORR to copy the data between
in input data structure and the procedure parameter.
Because the EVAL-CORR marries up the fields and performs type checking. It
also deals with Null capable fields, if you have those.

However, I see no obvious reason to prevent the use of a Ds likerec based

on an identical record format but only with a different name.
