You can generate the precursor of PDL, QSCHEMAC directly from an image data base with
the Cognos program ITOQ ("Image to Qschema"). I do not know whether Cognos still
supplies it on the tape. Once you have the output from ITOQ, it needs to be compiled
with the QDD utility, and again I do not know whether Cognos still supplies this
program. Once compiled, the PDL source commands to create the PHD can be milked from
the QSCHEMAC file via QSHOW. I do not have a QSHOW manual handy, but this step is
clearly documented. "QSCHEMAC" and "PHD" are formal file designators and can be
equated with the :FILE command to any file.

FYI, there is a PowerHouse e-mail list to which you can subscribe. Cognos support
personnel are active participants on this list. You can send a message to
