Error after executing shell$()

[sundale]

Having problem using shell$() command.

The command is executed, but resulting error condition.
The error message read:

Runtime Error in program 'priceUpdate': result$ = shell$("descupdate.bat")
KeyNotFoundError

Actually, the command has executed and I can see the result is OK.
But, due to error condition, my RB program stops.

WHY and HOW to make/disable the error condition

Thanks in advance!

Seems there is another DOS error code kicking in.

You may end your batch script with exit 0 to prevent returning an error code, when it runs all the way down to the end.

Thanks Stefan, it works!!!

Still I think you should investigate, which command returns the error code, just to make sure everything really works.

You are right.

But in some case, even if I use exit 0 I still have error condition.
So, I coded on error goto [doNext], but it seems on error is not caught, the system crash.

How to make sure at error condition goes to my [doNext] routine and resume?

-thanks

There seems to be an error in one of the used batch script commands, I think.
I would add a line to output the result of each batch command to be able to further investigate.

Example batch command:

DIR C:\
ECHO DIR returned %ERRORLEVEL%
