Signals the start of a block of chadd/chkey commands in a script file.

Nesting chadd/chkey commands inside a chblockbegin/chblockend block makes the commands much faster by deferring even propagation until the end of the block, then sending all events at once.

This command can only be used when sourcing in a script file. Calls can be nested, but each chblockbegin command must have a corresponding chblockend command.

You should only use chadd and chkey commands inside a chblockbegin/chblockend block. Otherwise dependencies may not be properly maintained.
