Nesting is supported up to five levels. An error message is displayed if there is incorrect nesting of WHILE conditions. An error message is displayed if a user tries to execute more than five WHILE conditions.
Ctrl-C can be used to break out of a WHILE loop(s). Breaking out of any number of WHILE loops always clears all the WHILE loops .
The operators mentioned in Using Operators can be used in an _expression in a WHILE condition.
