temporarily in a known state for debugging purposes. To set, force,
and unforce variables, you must have an online program window
open. You can set or force any global variable in the configuration or
any local variable present in a task that is loaded into the rack.

elementĆindexed or bitĆindexed variables. For example, you cannot
force variables like: vat.13, array_var[11], array_var[index_name],
array_var[11].12, or array_var[index_name].bit_name.
