Well, saving the reference is easy (I recommend the long id) ;-) using it is another matter. Although there are instances where you can use the object reference itself, sometimes you can't and will get an error - for example, with fields, you can set direct properties (the lockText of tFld, the showBorder of tFld, etc.), without getting an error, but chunk expressions will work on the variable itself and not on the reference. Compare: -- assume that fld 1 has 3 lines of text put the long id of fld 1 into tFld set the lockText of tFld to true --> works as expected, sets the lockText of the field put the the number of lines of tFld --> 1 -- since tFld is a fld ref and a single line of text, it returns 1 So to get around this, you need to use "do" in some instances: do "put the number of lines of" && tFld --> 3 Additionally if you use "put", it's not the same as if you'd addressed the field directly. Compare: put fld 1 --> puts the contents of fld 1 put tFld --> puts the field reference to field 1 do "put" && tFld --> puts the contents of fld 1 put the text of tFld --> puts the contents of fld 1 Personally I use "do" whenever *not* not using it fails - I don't think there's a downside to always using "do" when you have a long ID as a reference, other than that it takes slightly longer to process because it needs to interpret it on the fly (which really only shows itself when you have it in a loop).
