While

is a loop command that
repeatedly evaluates test-clause and executes loop-clause
sequence if the test is true. Because the test-clause is
executed before the loop-clause, the loop-clause is not
executed if the test is initially false. Its syntax is:
WHILE
test-clause
REPEAT
loop-clause
END
1
X
A:
WHILE A < 12
REPEAT A+1
X
A
END
FOR…TO…STEP

FOR A=1 TO 12 STEP 1;
DISP 3;A:

Note that the STEP parameter is optional. If it is omitted,
a step value of 1 is assumed.
