An OmniMark programmer can declare and call functions written in a programming language other than OmniMark. The external function declaration defines the calling sequence and initially specifies where these external functions are to be found on the system on which OmniMark is running. The programmer can redefine where to find the external functions at any time.
The interface that external functions use to access the OmniMark environment is designed to make it easy to write external functions that behave just like internal functions. In particular, external function programmers are urged to make use of the current output set and the currently selected items of function arguments wherever applicable.
For more information on writing external functions, see the OmniMark external function programmer's guide.
