Summary:	Invalid Variable name
Cause:	Undefined variable name. A variable name was specified that was either invalid or not defined. One situation where this error can occur is when a FORM variable is not defined. In the following example, the variable P is used to identify the POS position. If P is not previously defined, this error will occur during execution: PRINT USING "FORM POS P, N 12.2": D Break used in conjunction with an otherwise unused variable or internal function (like fkey) Break Off attempted for a variable that did not have break turned on
Remedy:	Define the variable. Check the spelling of the variable. if automating break points use a temp variable to remember if you turned break on for something so you can test if it needs break to be turned off before attempting to turn it off.
