•Ensure that Prog “file name” is not used to return from subroutines to main routine. If used, delete any unnecessary Prog “file name”. • Trace the subroutine jump destinations and ensure that no jumps are made back to the original program area. Ensure that returns are made correctly. Appendix Appendix Message Stk ERROR Mem ERROR Arg ERROR Dim ERROR Com ERROR Transmit ERROR! Receive ERROR! Memory Full! Meaning •Execution of calculations that exceed the capacity of the stack for numeric values or stack for commands. 1 Not enough memory to hold function input in the Graph Mode for graph drawing. 2 Not enough memory to hold function input in the TABLE Mode. 3 Not enough memory to store data in list function. •Incorrect argument specification for a command that requires an argument. • Illegal dimension used during list calculations. •Problem with cable connection or parameter setting during program data communications. •Problem with cable connection or parameter setting during data communications. •Problem with cable connection or parameter setting during data communications. •Memory of receiving unit became full during program data communications. Countermeasure •Simplify the formulas to keep stacks within 10 levels for the numeric values and 26 levels for the commands. •Divide the formula into two or more parts. 123 •Keep the number of variables you use for the operation within the number of variables currently available. •Simplify the data you are trying to store to keep it within the available memory capacity. •Delete no longer needed data to make room for the new data. Correct the argument. •Fix n, Sci n : n = integer from 0 through 9. • Lbl n , Goto n : n = integer from 0 through 9. •Check list dimension. •Check cable connection. •Check cable connection. •Check cable connection. •Delete some data stored in the receiving unit and try again.

(In the case of exponential display, calculation error is ±1 at the last significant digit.) Errors are cumulative in the case of consecutive calculations, which can also cause them to become large. (This is also true of internal consecutive calculations that are performed in the case of ^(xy), x y, x!, 3 , nPr, nCr, etc.) In the vicinity of a function’s singular point and point of inflection, errors are cumulative and may become large.
