Repeat DO loop
A repeat DO
runs a block of code
for the specified number of times, with a simple repeat count as the
argument.
For example, the DISPLAY command is run 3 times:
DO 3
DISPLAY “HELLO”
END
Use the ITERATE
command at any point in the block to start the next
iteration of the currently active loop from the DO
statement again. Use
the LEAVE
command to exit the currently active loop and resume processing
following the corresponding END
statement.
The ITERATE
and LEAVE
commands can be used only
to exit the currently active block.
