4GL Calling Stored Procedure ?

Hi out there, is there a possibility to execute a stored procedure from within a 4gl program. I didn't find anything in the documentation about that and trying to do this causes me compiler errors. It wouldn't be nice to write a separate esqlc-module just to execute a stored procedure, or even create a trigger therefore. I actually did write a esqlc-module and linked it together with my 4gl stuff, but doing this is always a PITA with all the pushs and pops. Thanks in advance
