Yes, the problem with pipes is that not every system has the named pipes of
SMSQ/E.
Just a quick pointer.
I had the same problem for the Proforma filter - how do I pass the PCP the
pipe in a Qdos system.
The way I did this was to
1 - open the pipe
2 - get the channel ID of the pipe
(all of this is done withing the PFF device, so MC code, so pretty easy.
3 "add" the channel ID to the pipe name.(length of name 8, 'pipexxxx')
4 - Pass that name AS A STRING to the job.
5 - Write the extention OPIPE.
This take the pipexxxx name, remakes the xxxx part back into a channel ID,
uses that to open the pipe for input, makes an entry in the basic channel
table and returns an Sbasic channel number
eg chan%=opipe('pipexxxx')
then use chan as normal channel number.
This can be found as part of the PFF extensions.
All you need to to is the inverse function (called, for example, "pipename",)
eg
open#4,pipe : rem open pipe for output
name$=pipename(#4)
this would return the name pipexxxx for the pipe.
Rich, you should be able to write that...
Hope this helps.
