Finally getting around to this... thanks!

One question about part of the code:
(07-18-2022, 07:16 PM)bplus Wrote:
Code: (Select All)
Function N2S$ (EXP$) 'remove scientific Notation to String (~40 LOC)
    ...
    ReDim t$, sign$, l$, r$, r&&
    ReDim dp As Long, dm As Long, ep As Long, em As Long, check1 As Long, l As Long, i As Long
    ...

Why ReDim instead of Dim?
I only ever use ReDim if I need to grow or shrink an array. 
But these don't seem to be arrays and are not ReDimmed later in the function, so is there any advantage for ReDim that maybe I don't know?
(I figure I might as well ask!)
Thanks again!

Good question,
According to Luke ( a developer of QB64.exe) and Steve or others may confirm, ReDim can be used anywhere you use DIM. Dim is the only command you want to use to make a Static array (cleared with Erase) unless you use Static itself.

So I modified that code (that came from Steve BTW) with REDIM's probably to make Option _Explicit happy back in the period when I was using REDIM for everything except Static Arrays. 

What I like about this is no Type worries for the number!
b = b + ...
