Re: Let versus Move

[Manoj Chainani <mchainani@HOTMAIL.COM>]

Hi Joe,
Refering to your question regarding difference between Let and Move, the
only diff. that I can think of is that in 'Move' you can provide an edit
mask, which I don't think you can do using 'Let'
eg. Move 0 to $numb 99.99
The statement which you have given containing both Let and Move on the same
set of variables, well, probably the programmer might have thought that if
one doesn't work, the other might (just kidding).
