call .m script files from within .oct's

[Artur Jorge Azevedo Carvalho]

hi! could someone please tell me how in the hell can i make a call to a
.m script file from within a .oct file?
what i'm planning to do is make a call back function using a .m file as 
the callback, so i also need to pass the func as a parameter to the .oct 
file also, is it possible? i supose that they're all avaiable in some 
array of funcs, maybe i'll just need to pass the name of the func as a 
string and use some octave func to make the call, no?
thanks in advance!
