Hello,

Several people answered this already. You do NOT have the Solve app running/selected when you are editing your source file. Thus when it checks the code, it can't find SOLVE which is a solve app function and not a global system function

Solve.SOLVE fully qualifies the command and tells the system where to look. You currently have a dependency on the Solve app being active to use your program.

Solve.SOLVE replacing "SOLVE" would fix it.

SOLVE is basically identical to FNROOT. You aren't simultaneously solving with SOLVE - it can't do that. FNROOT is a drop in replacement in your source and will have no dependency on the solve app. If you got rid of storing into E1, you'd no longer be using anything in the solve app.

FNROOT(X^2-2,X,-2) -> ~-1.41
FNROOT(X^2-2,X,2) -> ~1.41
