Word data is extended to long word data with a sign in the MC Unit.
• If Conditional variable specified in SWITCH command matches Condi-
tional constant specified in CASE command, only processing between
CASE command with the matching constant and BREAK command will
be executed.
• If Conditional variable does not match Conditional constant in any of
CASE commands, processing between DEFAULT and SEND commands
will be executed. If DEFAULT block is omitted, nothing will be executed.
• CASE command within processing 1, 2, and N is ignored, which means
that the same processing can be executed under a different condition.
• There is no limit on the number of CASE commands (actually, the number
of blocks per program limits it).
• SWITCH command cannot be used within processing 1, 2, and N (selec-
tive branches can not be nested).
• Processing 1, 2, and N can be described over multiple lines.
