This message is to request some help with a printing problem I
have been wrestling with now off and on for some months and it
continues to kick my behind.  The following is background infor-
mation and then a description of the problem.  I am also upload-
ing a file called RPTDMD.ARC which contains the source code, a
test DBF, the file I use to start the main program with (has SET
CLIPPER=R095;E000 in it), and a sample output file complete with
printer codes.

Background:
Machine: HP Vectra 8hz, w/Core International AT-43 hard drive on
         a Perstore controller (87 meg), 2MB AST Above board
Config.sys - for test purposes 2 lines - FILES=25; BUFFERS=8
Autoexec.bat - for test purposes - not used
DOS - IBM 3.3
File - FILRPTP.PRG part of a larger program called PJLMNU which 
         is a project list database.
Printer - Okidata 192+ (IBM Graphics) or Epson 286e (tried both)
Same problems when run on an IBM-AT with no expanded/extended
memory, a XT clone with 1MB expanded memory, or HP vectra with
floppy drives only.  All had basic config.sys file and no
autoexec.bat thus no memory resident programs. No disk cache.

Problem description:
Computer locks up requiring cold boot during printing.  Occurs
randomly during the printing cycle, sometimes only the page
heading prints and then printer goes to continuous form feed. 
About 10% of the time will print report with no problems.  When
using Debug it seems that the memvars all of sudden all get
contaminated (scrambled) but because of randomness I don't know
why.  When I hard code the Public memvars which are initiated
elsewhere and compile and run the program by itself it seems to
be work all but about 25% of the time.

Any help would be certainly appreciated.
