Monitor program so it's status can be a variable for script

[Tolgod]

Hi there. I've been busy lately to learn more about scripting to make my life as an Amigan/Vampirian easier and have lots of fun doing that along the way.
Currently I'm busy with something that would require me to startup a program via script using wbrun.
This program is dependant on something else, which I startup earlier in the script.
No what I want my script to do is monitor the status of the program I started using WBrun periodically. If it is still running the script waits and then LAB's back to monitor/check again, when the program is no longer running, the script continues and closes down whatever was started that the main program was dependant on.

Is this possible to script?
Preferably the arguments are generic, meaning that I always will know what name the proces will have to monitor.

ie

check status <name of program started / name of proces started by program)

If running a program leads to dynamic assiging of attributes that could be monitored, I would like to see if it could be steered in a fairly fail proof manner.

ie

wbrun program as <controllablevariable> (here some proces number or other parameter would be used that is extremely unlikely to allready be in use.

If this would also not be possible, I would like to see if a wild card manner of checking status is possible.
This would lead to the logic : If a proces containing <unique identifier for started program> is running do this, else do that.

I hope I have been able to bring across what I want in a understandable manner and look forward to finding out what is possible here and what not.

Tnx in advance for any assistance.

If I understand you right you want something like interprocess communication. As far as I know AmigaDOS has not something like this. With ARexx you could use message ports or maybe SETCLIP()/RXSET and GETCLIP().

Hi there. I think indeed you understand what I want. To put the mechanics into words I'll illustrate as follows.
Script :
Startup whatever program need
Startup program
Label 1
Check program status
If program is running
Wait 1
Skip to label 1
Else
Stop whatever program needed
Endcli

This is the working I'd like to achieve, if possible.

If this can not be scripted, what would be the easiest to get my head around to program this. Arexx has the reputation of being fairly complex from what I've read about, maybe some simple basic programming could suffice?

Are you 100% complete sure wbrun is the only option ?
What happens if you just run your program as normal cli program ?

Yes, I would try

run >nil: needed_program
program
rx "address needed_program's_port quit"

If you are not using ARexx, the 'status' command can help you

status COMMAND <command_name>

Will return you the process number that your command runs into.
You can assign the result to a variable and test it within your script.
If the variable is empty, it means that your command ended.
