Appendix B: Technical Reference
A transmission between two units was not completed. Verify that the
connecting cable is connected firmly to both units.
The calculation required more memory than was available at that
time. If you get this error when you run a large program, you may
need to break the program into separate, smaller programs or
functions (where one program or function calls another).
Using the interactive math features (F5:Math) in the Graph
application can give this error. For example, if you attempt to find an
inflection point of the parabola y1(x)=x
error will be displayed.
If a is the name of a PIC, GDB, MAC, FIG, etc., a+1 is invalid. Use a
different variable name in the expression or delete the variable.
For example, if the unit is in the REAL setting of the Complex Format
mode, ln(-2) is invalid.
This error message is caused by very low memory conditions inside
the Data/Matrix Editor.
