Anyone aware of any issues with this - especially on VMS?

Hi,

One point to note is that for RMS files the locking is more "stringent" than PRO-ISAM OR C-ISAM. By this I mean that if you lock a record then it is locked to the same function. HTH

There is no record locking in Add mode except when using Pro-ISAM (and possibly Reality/X).

You could use a pro-isam locking file with the same keys,
and read it before adding to the non-pro-isam file, and then
just dself on before write, so the file stays empty.

You can't do this on VMS! You only have RMS files (either in ProIsam internal format or in fixed external format) - but the record handling is pure RMS.

Or the AS/400, where you only have DB2/400.

What about the installation option with V5.5 on VMS:

Enable Add mode record locking [N] ? :


What does that do with RMS ?
And with Oracle tables?

I thought it was causing me a problem, turns out not to be
but I'm still a little unsure what's going on.
