Re: LVLCHK(*NO)

In my experience, existing read-only programs are unaffected. Existing
programs that use RLA to do inserts/updates can fail, usually when a new
numeric column is added. Since the program I/O buffer doesn't know about
those new columns, it can't ensure valid data per the column data type.

Hi,



I was rather surprised to discover that in my current shop, it is a regular
practice to use files in this way, thus avoiding (sometimes) the need to
recompile some of the programs sources where they are declared.

I?ve just modified such a file, placing a couple of new fields at the end
of the DDS. The program seems to function normally. But what happens
exactly when the program reads the file ? Surely, the memory pointing to
the new data somewhere is modified. Where is it and how can one be sure
there can be no ill effects ?



Thanks !
