If you use the CALL command in a batch file to execute an .EXE file and use
appending redirection (>>) to save the output to a report file, files
remain open for the number of times the redirection is used.
Remove the CALL command from the batch file. The CALL command should only
be used in batch files as described on page 377 of the "Microsoft MS-DOS
User's Guide and Reference" for version 5.0, and MS-DOS online help for
versions 6.0 and 6.2.
The above has been verified using Quarterdeck Manifest version 1.1.
The following example batch file and steps demonstrate the problem:
• Create a TEST.BAT file (substitute your Quarterdeck directory for
ECHO **MANIFEST REPORT FILE** > C:\QDECK\REPORT.DAT
CALL C:\QDECK\MFT S O >> C:\QDECK\REPORT.DAT
CALL C:\QDECK\MFT S C >> C:\QDECK\REPORT.DAT
ECHO **END OF REPORT FILE** >> C:\QDECK\REPORT.DAT
• Execute Manifest MFT.EXE and check number of files open under the
• Run TEST.BAT.
• Execute Manifest MFT.EXE and check number of files left open after
the batch file has run.
There should be two more files left open (both REPORT.DAT) in step 4
than were in step 2. Adding more (CALL C:\QDECK\MFT >>) to the batch
file or running the TEST.BAT file again will cause more files to be
left open. To close the open file handles, you will have to restart
