Hello!


create or replace library libc_1 as '$1$DGA3:[BENBHM.USERS.LK]test.olb'

.OLB ? :-)

[Hein van den Heuvel]

Ah yes, I missed this entry earlier.
Ruslan is right about the .olb observation.
The library should be an shareable executable typically called .EXE and created uning 'lnproc' ?

Of course you can be 'cute' and call the EXE file .olb, but that just spells trouble.

Cheers,
Hein.
