vrf HP4156 panel driver

Not me.  But I understand driver code.

That line of the code is selecting a case for const_op_tmp_store -- which is a string.  It apparently has a value that was not expected 12 years ago.

Possibly.  Or your instrument has newer options than the code.

> Are the panel driver codes reliable or can we expect them to have bugs.

Some are reliable (at least the ones Jay and I wrote , but most are obsolete.  Newer options have been added to the instruments that the drivers can't handle.

> If this is a bug, can I get a correct version of the panel driver for

I think there is a Plug&Play version available.  It might work better.  At least it's newer.
