R4GL func call from C ?

I am currently porting an application from V4.00.UE2 I4GL to V4.00.UH2 RDS and this has raised the following problem; There is a c function, carries out some text processing, which itself calls a 4gl function, after pushing the relevant variables onto the stack. I would like to know if anyone knows of a means by which a 4gl function can be called from within a c function when using custom runners under RDS. please email me with any advice/info/etc....
