Hi Guys
I wish to use the watchdog command to restart a program should it get itself into a loop or some sort of program failure.
I have the watchdog instruction in a section of the program which is named autorun.bas
What what do I place in restart.bas
I tried the one line: run autorun
but it didn't seem to restart when it crashed.
Have I got this correct.
From what I can gather from The Back Shed forum that is all I need.
I have a CMM running Ver 4.5 with both files on the b: drive (SD card)

Regards
Chrisk

Hi Chrisk,

Not too sure on this one but does your one-line need to include quotes?

So restart.bas contains: RUN "autorun.bas"

No doubt someone will chime in here too to prove me wrong!

Start with a PRINT "OOPS!!!"
in the restart.bas file so you know that you got that far.

I think you need quotes around the file name for the RUN command
run "autorun.bas"

Thanks WhiteWizard and TassyJim.

It was those double quotation marks that were required.
Not sure why they are needed but it worked.
For future reference I should point out I was using TeraTerm and when restart.bas ran the USB communications no longer existed. So no "OOPS!!!" was viewed.
The main thing is I saw that the main program restart.
I gives me that confidence that it will restart should I not be in attendance.

You where a great help.

Chrisk

The double quotes tell the MM that "autorun.bas" is a string and not a variable.

You could also define a string variable to use instead.

A$ = "autorun.bas"
Run A$
