Setting command.com initial environment from Delphi GUI

I have a Delphi 3 program which creates a batch file based on selections made by the user. I then use WinExec( ) to run the batch file.

The problem is, when WinExec opens the DOS Shell (in order to run the batch file) the DOS Shell does not have the correct initial environment size (4096 KB) needed for the batch file.

How do I programmatically set the initial environment so I don't get "Out of environment space" when I run the batch file?

Please...only submit comments for now. If a comment works, I'll have you resubmit the comment as an answer.

Thanks!

Try this one:

WinExec('C:\Command.Com /E:4096 /C C:\YourPath\YourBat.bat');

Does that help?

I should think that you would be able to do this via the commandline parameters:

COMMAND [[drive:]path] [device] [/E:nnnnn] [/L:nnnn] [/U:nnn] [/P] [/MSG]
[/LOW] [/Y [/[C|K] command]]
[drive:]path Specifies the directory containing COMMAND.COM.
device Specifies the device to use for command input and output.
/E:nnnnn Sets the initial environment size to nnnnn bytes.
(nnnnn should be between 256 and 32,768).
/L:nnnn Specifies internal buffers length (requires /P as well).
(nnnn should be between 128 and 1,024).
/U:nnn Specifies the input buffer length (requires /P as well).
(nnn should be between 128 and 255).
/P Makes the new Command Interpreter permanent (can't exit).
/MSG Stores all error messages in memory (requires /P as well).
/LOW Forces COMMAND to keep its resident data in low memory.
/Y Steps through the batch program specified by /C or /K.
/C command Executes the specified command and returns.
/K command Executes the specified command and continues running.
