Thank you! I think that is exactly what I am looking for. i have found VFP params in remote views work pretty much the same as variables in TSQL when they are translated into SPT so I suspect parens around the ? param will make it work.

But to test in real SPT rather than waiting until I finish the remote views DBC, I need to establish a connection in VFP from the command window .,..

Could you refresh my memory on getting a connection in VFP to a system or file dsn from the comman window?

I have a system dsn ITF that uses a trusted connection (perhaps VFP is not seen as such?)

nConnectionHandle = SQLCONNECT('ITF') gets a -1
I created a file DSN and put in in my VFP path ITFDSN but nConnectionHandle = SQLCONNECT('ITFDSN') gets a -1 as well

Am I doing something boneheaded or does this stuff not allow trusted connection or ...

TIA

Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.

Liberty is a well-armed sheep contesting the vote.
