Dim strTest As String ' "Pointer" to a "Blue Print" (or Form, Questionnaire not yet filled in, a template etc.)"Pigeon Hole" in Memory, sufficient in construction to house a piece of Paper with code text giving the relevant information for the particular Variable Type. VBA is sent to it when it passes it. In a Routine it may be given a particular "Value", or ("Values" for Objects). There instructions say then how to do that and handle(store) that(those). At Dim the created Paper is like a Blue Print that has some empty spaces not yet filled in. A String is a bit tricky. The Blue Print code line Paper in the Pigeon Hole will allow to note the string Length and an Initial start memory Location. This Location well have to change frequently as strings of different length are assigned. Instructions will tell how to do this. Theoretically a special value vbNullString is set to aid in quick checks.. But..http://www.mrexcel.com/forum/excel-questions/361246-vbnullstring-2.html#post44116
