HP 39g Matrix commands

WHILE…	While ... Repeat ... End is a loop command that
REPEAT…	repeatedly evaluates test-clauseand executes loop-clause
END	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 name=start-expression TO end-expression
...END	[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.

Matrix commands
	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
	commas and the number of values must be the same as
	the number of rows in the matrix name.
	ADDCOL
	name;[value1,...,valuen];column_number:
ADDROW	Add Row. Inserts values into a row before row_number in
	the specified matrix. You enter the values as a vector. The
	values must be separated by commas and the number of
	values must be the same as the number of columns in the
	matrix name.
