Thank you for the information.  What do you plan to do with it?  Sounds
like it is suited toward tasks done in a batch processing script.  Is
that what you want it for?

Do you ever wonder that if a programmer learns too many programming
languages, his head would explode?  :-)

Restored when the block ends?   From that description it sounds like you 
are converting a local variable to a global variable. (?)
 
If what its doing is taking a global variable, saving its value,
re-using the variable for a "local" subroutine, then popping the
original value back into it... then why not just use a unique variable
name to re-use in every local function where we don't care what its final 
value is ( a variable named "Temp" for example )?
