About commands

Matrix commands are listed in the CMDS menu (|shift|

CMOS), in the matrix category.

See “Matrix commands” on page 15-23 for details of the

matrix commands available for use in programming.

Functions differ from commands in that a function can be

used in an expression. Commands cannot be used in an

expression.
