Handling of structures as function argument

[MichaelHuth]

Structures can be given as function argument as MRS element or both. Every variant is internally a function argument by reference.

Structures should be only used as MRS element if the structure elements are written before possibly read in the function.

If a structure element is read first then the structure argument should be placed as function argument.

static Structure teststr
	string str
EndStructure

Function test()
	STRUCT teststr s
	
	[s] = AsMRS()
        AsArgument(s)
        AsBoth(s)
End

Function [STRUCT teststr s] AsMRS()

	s.str = "written"
	
	return [s]
End

Function AsArgument(STRUCT teststr &s)

	print s.str
End

Function AsBoth(STRUCT teststr &s)

	print s.str
        s.str = "written"
End
