Problem with -208 in DOS.

We are having trouble with the -208 error while running the following setup: 386/33 with 8 megs of ram Informix SQL v2.10 Informix 4gl v1.10 MS-DOS v5.0 & 6.2 Our config.sys : files=40 buffers=10 device=c:\\dos\\himem.sys /int15=2048 dos=high,umb device=c:\\dos\\smartdrv.sys 1024 512 shell=c:\\command.com /e:1024 /p Our autoexec.bat : PROMPT $P$G SET PATH=C:\\;C:\\BATCH;C:\\INFORMIX\\BIN;C:\\HWS\\BIN;C:\\WP51 SET HWSDIR=C:\\HWS SET INFORMIXDIR=C:\\INFORMIX SET DBCOLOR=BLACK/CYAN SET DBPATH=C:\\HWS SET DBEDIT=C:\\HWS\\BIN\\VI SET DBTEMP=C:\\TEMP After approximately 6-10 transactions (going in and out of screens, using pick-lists, saving data, etc.) we begin getting -208 errors. The book indicates it is a memory allocation error, but offers no fix. Does anyone have any ideas? Is this a memory leak issue? If so, is there a way to do garbage collection with memory without having to leave the application? Please reply to severa@delphi.com and/or this usenet topic. Thanks. Oh, the reason for using the older version is due to client limitations. We will be 'porting' the application to windows 4gl soon. lWould appreciate anyones input.
