WHILE…
REPEAT…
END
While ... Repeat ... End 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
...END
FOR name=start-expression TO end-expression
[STEP increment];
loop-clause END
FOR A=1 TO 12 STEP 1;
DISP 3;A:
END
Note that the STEP parameter is optional. If it is omitted,
a step value of 1 is assumed.
BREAK Terminates loop.

The matrix commands take variables M0–M9 as
arguments.
ADDCOL Add Column. Inserts values into a column before
column_number in the specified matrix. You enter the
values as a vector. The values must be separated by

the number of rows in the matrix name.
