Re: [sc-users] using a custom function in classes

[LFSaw <lfsaw@xxxxxxxx>]

Hey,

you may want to create a class collecting such functions as classmethods

MyFunctions {
	*nthFactorial {...}
}

which you then can use from within other Classes:

B {
	b {
		^MyFunctions.nthFactorial();
	}

}

lg + hope that helps
	Till
