Re: Subfile Read without Update error.

["Joep Beckeringh" <joepb@xxxxxx>]

Rajeev,

RPG processes the display file as a file, i.e. there is a file pointer to
the current record.  When you do an update, the current record is updated
and released.  When you read a record from subfile A, that record is the
current record and can be updated.  But as soon as you read a record from
subfile B, the record from subfile A is released and the record from subfile
B becomes the current record.  When you update that record, it is released.
If, after that, you try to update the record from subfile, you get an error,
because you released it by reading the record from B.

Solution:  like Joe Teff suggests, either do the update before you read any
other record from the display file, or save the record number and chain
before you do the update.
