variable for type's fieldname?

Can't you just use an array within a type?

ArraySectors(SectorNumber)\ParameterName[pm] = ParameterValue

Notice the square brackets (not parenthesis)...

Type atype
	Field normalfield
	Field anarray[50]
End Type

typeinstance.atype = New atype
typeinstance\normalfield = 5
typeinstance\anarray[4] = 27

Print typeinstance\normalfield
For iter = 1 To 10
	Print typeinstance\anarray[iter]
Next
