Usage	This tag allows the creation of global variables in a similar manner to the iSET tag. Multiple assignments can be made on one line. Variables defined with this tag are available to all iHTML enhanced pages on the web server. This could be used within a site to track the number of users by incrementing the value on each page.
Note	If you define a local and global variable with the same name, the local variable will be used. It is recommended that you preface global variables with g_ to differentiate them. When combined with the bootload and bootdown feature in the Enterprise edition, variable contents could be saved between server shutdowns and startups.
