Command description
END-WHILE terminates a WHILE block, i.e. a loop which was initiated with the WHILE command.
The loop condition in the WHILE command is checked during execution of the END-WHILE command. If the condition is met (TRUE), the first command in the WHILE block is used to start the next loop pass. Otherwise, the loop is terminated. Procedure execution resumes with the first command following END-WHILE (for further details see “WHILE block” (Defining loops )).
