of calls is 5.

Set Analogue Value
Sets the specified analogue parameter to the defined value. If the value is outside
the parameter's allowed range, then the parameter will be set to the nearest limit.
It will not step on to the next instruction if the parameter is disabled.
Set Co-ordinate Valoe
This instruction perfonns the same action as set analogue value except that it
sets the value for a pair of parameters making up a co-ordinate pair (x and y).
Stage Goto
This instruction moves the stage to the defined X, Y and Z co-ordinates. It does
not step on to the next instruction if stage movement is currently disabled.
Wait For
The wait for instruction waits until the specified state is achieved. An optional
timeout parameter may be specified (in seconds) which limits the amount of time
the instruction will wait. If no timeout parameter is specified (not zero seconds,
but no characters) then the instruction will wait for the state indefinitely.
Delay
This instruction waits for the specified number of seconds before continuing.
Pause
The pause instruction acts in the same way as the pause key. It causes the
execution of the Macro to be suspended.
