Cryptic Error Message

[veeblefester]

The following error message occurs at runtime.

'Unmatch control word' (Unmatch is not a typo)

I could not find any description in the Prime User Guide.

Does anyone know what this means?

Thanks in advance for any help.

This can mean several things.

1. You created a function that requires a certain number of inputs, but when you actually called the function you did not specify the correct number of arguments. For example, your function requires PROG(a,b) but you used PROG(a). More generally, there is a function call that is not matched with a program block.

2. You used graphics objects G0 through G9 and the program was compiled within the Spreadsheet app. The program compiles fine but it will not run properly. Switching to another app does not fix the problem. Instead, compile the program in a different app view. This is currently a firmware bug. (Compiling here simply means open the source file and then exit from the program editor).

I'm sure there are other explanations, but these two are when I've encountered such error messages.
