HP 50g Programming functions to be used in the EQW

[Jun0303]

Good morning,

These days I've been programming some functions with UserRPL in the 50g HP and I was wondering how can I code a function that can be used in EQW. I mean functions like COS(angle) or F0ʎ(ʎ,T), that when I select then through the CATALOG of commands they appear in the Equation Writer with parentesis and the nº of value sthey need to work.

My function is something like:

<< → n p
<<
code of the function
>>
>>

and I included it in a library using HPLibs library to create my library but when I used in the Equation Writer it says "→ Error: Too Few Arguments", so how can I create a function that the Equation Writer asks for the arguments?
