[ROOT] Executing a loaded method

Hi rooters,

I am developing some user interface in which users can apply some simple 
macro (either compiled or interpreted) to several events. I first load this 
Macro with gROOT->LoadMacro() so it is not loaded several times (with 
related warnings). Then I would like to execute the main method (with the 
same name) with some arguments comming from my user interface program. The 
problem is that gROOT->ProcessLine() does not work: it seems to open some 
new temporary TFile in which my arguments (although my program is mainly in 
interpreted mode) are not recognized. The only solution that I see 
currently is making a new macro file on the fly in which resides only the 
call to my function with corresponding arguments. Yet this can only work as 
long as my program remains interpreted. What I would like to do is get back 
my method (which is not a class method) from some TCollection (yet I didn't 
find which one) where from I could execute it directly with arguments, in 
both interpreted mode and compiled mode.

Could someone help me on this,

Best regards,

Martijn Schellekens
