'Opens, maintains, then closes a popup box to be used when
'copying a file or performing other task, to pacify the user
'while he waits.

'Switch% = 0 turns it on
'Switch% = 1 maintains it
'Switch% = 2 closes it
'Pass to it, a number between 1 and 100 and the proper switch
'PercentBox 0, 0  'you must 1st open the box
'PercentBox 1, (Percent%) 'maintain it with this.  Percent%
'    MUST be in parenthesis or else MUST be a numeric value.
'PercentBox 2, 0 'close it with this
'give it a number between 0 and 100, and increment it as needed
'the delay's, STEP, and for/next are for demo only

'I haven't tested this except in this program.  It could need some
'modification when run in a real program. <Oh well> :)

'inspired by reading in the conference.. Wellerstein to Goldbloom
'BTW, Alex, I liked yours, never got James' to run. PB, I guess :)

'I feel like the shipwrecked sailor, sending messages in a bottle.
'If anyone sees this message in a bottle, I sure would like to
'hear about it.  I've been posting messages since feb, and the
'only response that I have gotten was the one the other day from
'Joe.  I'm hoping that I am now making the trip! :)
