RE: Special file parameter issue

Rick,

Have you looked at creating a SQL VIEW which duplicates the old physical file layout but is built over your new file structures? With SQL you can also create INSTEAD OF triggers to allow inserts, updates and deletes on the view. If you use the same file and record format name in the view you might not have to make any changes to the RPG programs.

Subject: Special file parameter issue

I am attempting to use a special file program to handle I/O for a file conversion we are contemplating. The issue I am having is that the parameters aren't changing between a write and a read operation. I want to test the error handling if a read operation fails. I can't get it to fail because the parms passed are the same ones I used to add a record even though I explicitly change them in the caller. Any ideas?

Caller:
fLNP00507 cf e Special PgmName('LNP00507R')

d TEST507 pr ExtPgm('TEST507')

/Free

lxBk = 8;
lxMDte = 092210;
lxMemo = 'Special file test memo';
lxNote = 123456789;
lxRec = 1;
Write LNP0057;

lxMemo = ' ';

lxNote = 3;
Read LNP00507;

If Not %EOF(LNP00507);
Dsply %Subst(lxMemo :1 :25);
EndIf;

*InLR = *On;
