Scoping

Variables assigned outside of any block are global and visible to all blocks. A variable assigned within a block is visible only within that block.

Inside a block, you can assign a variable as a global variable, which is visible within other related blocks. Use the following syntax:

global a = 5.2

The following table describes what blocks are related with respect to scope:

Global variable set in	Effective in
outside of the lifecycle blocks	all blocks
the prejob block	all blocks
the pretask block	pretask, task and posttask
the task block	task and posttask
the posttask and postjob blocks	that block

Note that assigning a variable with the same name as a previously defined global variable does not change the value of the global variable. Instead, it creates a new local variable in the block, and that local variable has local scope and does not change the value of the global variable.
