I blanked on the | and ||.

It makes sense to me, I see it, I'm filing this email as a keeper
because I know I'll need to go back and refer to it. At this point the
best way to proceed for me is to worry less about all the code that
needs to be inside a block and create the scaffolds for the blocks
first with some puts statements just to makes sure things are
branching correctly.  I started with the original code I posted in
this thread.  I dropped the 'while' loop completely thinking it didn't
make sense considering the array loop was already in place performing
the same behaviour.

Dir.chdir 'C:/PicturesMoved'
pic_names = Dir['C:/PicturesMoved/*.{BMP,bmp}']

     pic_names.each do |name| # (1) array loop
          puts 'Do you wish to move ' + name + 'file?,"yes" or "no" ?'
          decision = gets.chomp.downcase

               if decision == 'no' # 1st if statement
                   puts 'This file will not be moved'
               else
                   puts 'This file will be moved'

               end # end for 1st if statement
     end # end of array loop

This seems to work fine, however if I add this to the 'if statement'
                           if decision == 'no'
                           pic_names.delete(name)
                           puts 'This file will not...........
                              else .........
                           end......

Then the next file in the array is skipped.  As an example, if it's
'pic1' and I say 'no', then the next name to come up for the gets
statement is 'pic 3'.  I never get to decide on 'pic 2' (saying yes to
moving 'pic 1' moves the next gets to 'pic 2')

So I decided to see what elements is assigned to
'pic_names.delete(name).  It's correct (i.e. no to pic 1, puts  'This'
+ name + ' will not be moved' , returns
This C:/PicturesMoved/copypics01 .bmp will not be moved. Yet right
after that prints out I get:
Do you wish to move C:/PicturesMoved/copypics03 .bmpfile?,"yes" or "no" ?
Not sure what happened to pic2 ?

I sense that I may still (as simple as this looks) some errors
somewhere in if / else.
