Do all programs require system memory to be allocated? When I run change program (CP) to display/alter the DVP it shows zero K system memory allocated but if I display the DVP with PIFEDIT (see DVPIF10.ZIP in the DESQview directory on SIMTEL20), it shows 5K of memory memory allocated.

Quarterdeck recommends that you DO NOT allocate any system memory UNLESS the application specifically indicates it is required. Perhaps there is some system memory always allocated but DV doesn't include that in the number showed in the CP command. /^/|^| Alan Claver, Microcomputer Info Specialist |^|\^\ / / | ||^| Penn State University Libraries |^|| | \ \ /_/ |_||_| E6 Pattee Library, University Park, PA 16802 |_||_| \_\ Ma Bell:(814) 865-7213--Bitnet:ALC@PSULIAS--Internet:ALC@PSUVM.PSU.EDU "In a calm sea every man is a pilot." -- John Ray

The system memory displayed in Change a Program is *extra* system memory, above and beyond that needed to hold the virtual (shadow) screen, interrupt vectors, DV internal stuff, etc. The .DVP field includes that overhead. For an example of a value smaller than 5K, look at the Memory Status .DVP. With a maximum screen size much less than 80x25, you'll also get a smaller system memory value. -- {backbone}!cs.cmu.edu!ralf ARPA: RALF@CS.CMU.EDU FIDO: Ralf Brown 1:129/3.1 BITnet: RALF%CS.CMU.EDU@CARNEGIE AT&Tnet: (412)268-3053 (school) FAX: ask DISCLAIMER?

The two things that SEEMED to solve this problem were: 1. Allocating more system memory to some program (the main trouble maker beening Xtree Pro Gold). 2. Increasing Common Memory to 30K. Allthough none of those is recommended (nor properly documented), it seems to do the trick. If anyone out there KNOWS what those options are supposed to be used for, and how to figure out the right parameters, Please inform me. Gil
