User defined Special Functions for calculator in algebraic mode.

nirmal21

Hi,

I wonder if anyone is able to point me in the right direction.

I have written a special function for use with the calculator following the instructions in the user guide. I am able to return my expression to the calculator using the calSpecialFunctionInput in a callback after filling in a form, and this works perfectly well when using the calculator in RPN mode.

However when switching to the algebraic mode of the calculator, the form does not seem to return anything to the calculator. I then created a form specially for the algebraic mode and used the calCalcInput function to return back the expression. However this overrides the expression already present in the buffer of the calculator rather than appending to it. I would like to replicate the same behaviour as existing special functions (say the eyeDiagram function) when returning expression to the calculator in algebraic mode.

I am using ICFB 5.10.41 and the calculator in AWD mode. Any help or examples would be useful.

Thanks.

Regards

Nirmal

 

  • For anyone interested,

    I solved this by using "calSpecialFunctionInput" in the callback and ensuring that the field in the algebraic forn that I used to load the first argument from was called "sfbuf". I wish that this was actually documented somewhere.

     I also found the other undocumented function "calGetCalcMode" to be useful when deciding which of the two forms to call. (alegebraic or rpn)

    Regards
