I often use global variables inside a unit or inside a component, when the
number of parameters in the procedure is starting to increase.... makes the
code easier to read.
Best to avoid them, partly for the risk of duplicating one - and then the
IDE displays the value of one, half your code uses one and the other half
uses the other. I keep plaguing Borland to atleast include this as a
compiler warning.

Hi
Another Newbie question.
What are the pro's and con's of either
passing a parameter to a procedure
versus
setting a global variable that the procedure can read?
