Error in Plato 3

I am doing a number of matrix multiplies and matrix modifications. I get a message to the effect that a variable or function is undefined within one of the matrix routines. It stops on a simple 'a(k) = - a(k)' statement. However when I leave Plato, compile the program using the command line compile-linker, the program runs just as it should with no errors.

It sounds like you are using different compiler options when you are working outside of Plato. For example, you may be using CHECKMATE within Plato but not from the command line.

Try stepping through the program using the debugger to see if an array element has not been set before use.
