N1 (XXX) or N2 (XXX.X) format depending upon the current numeric mode.
Negative values are preceded by a "-" minus sign.

Devices:

Turntables

Syntax:

CL?

Response:

[-]XXX[.X]

CL 1050/1060, CL 1090/2090

Compatibility:

1050, 1060

Description:

Query the current position. The value returned is either in N1 (XXX) or N2
(XXX.X) format depending upon the current numeric mode. Negative values
are preceded by a "-" minus sign. Towers return current position in
centimeters, turntables return it in degrees. This command is obsolete. On
the models 1050 and 1060, this command changed the front panel to display
the current position and prepared the controller to respond to all future reads
with the current position. This is not compatible with the IEEE 488.2
standard; the program must send the CP command before each read. For
programs which will not be used with a model 1050 or 1060, use the CP?
command.

Devices:

Towers, Turntables

Syntax:

Response:

[-]XXX[.X] Value

the current position in centimeters for

towers or degrees for turntables.

Example:

CALL ibwrt (TowerUD%, "CP")

' Query tower current position

CALL ibrd (TowerUD%, rdbuf$)

' Read response

CALL ibwrt (TableUD%, "CP")

' Query turntable current posn

CALL ibrd (TableUD%, rdbuf$)

' Read response
