Parallel API troubles...

Hi,

I'm trying to implement the parallel api and make use of it but I'm having a very diffiuclt time with it. No errors occur I'm just not able to get it to run both functions. I'm guessing it's I just don't understand enough of how the API works to properly modify my code. If anyone could help me make this work, I would be very grateful!

This program basically will listen for a rednet message, split the message, compare some values from a global table variable and then send a reply back. However, I wanted to be able to have a prompt so I can change values while the program is running to prevent downtime. The code I have below probably has a few testing bits in it well I was trying to make this work but I think I removed most of them. I eventually will be releasing this entire program once I finish the other half of it.

If you would like any more information just let me know please. Thank you in advanced!

parallel.waitForAll(prompt(), function() shell.run("shell") end)
--parallel.waitForAny(prompt(), main())
end

You need to give the functions as arguments, you don't have to call them:

paralle.waitForAny(prompt, function() shell.run("shell") end)

Ah! Thank you! That seems to have fixed it. I'm not 100% sure (need to build the client part still) but the rednet turned on so that means it's working believe.

Basically based on what you said, I don't need to do prompt(), i do just prompt (Without the ()'s)

Thank you so much! :(/>/> Been trying to figure that out for a few hours lol.
