On one machine we have three operator command windows and on the other, we only have two. Is there a command to activate the third?
one machine has: bt-basic window graphical interface window menu window along the top - listing "start" "stop" "quit" "fixture lock" etc. (function keys) this is the one that is missing on our other system
I'm not very sure if I understand your question anyway let me try to answer.
I am assuming that you are missing the operator keypad whenever you turn on the testhead (Testhead power on or testhead is 1). It is possible that the operator dispaly is off also. Below is the explanation of Operator syntax taken from the 3070 on line manual
operator (BT-BASIC) Title: DISPLAY THE OPERATOR KEYPAD The operator function causes a labeled set of boxes called the operator keypad to appear at the top of the screen. Each of these boxes performs a function that can be executed in one of these ways:
Touching the appropriate button (if the monitor has a touchscreen). Using the mouse to click the appropriate box. Pressing the softkey, f1 through f8, that corresponds to a box on the screen. (This works only when the cursor is outside the operator keypad.) There are multiple sets of boxes and functions available; which set is invoked depends upon which is specified in the operator function.
The softkey labels and functions are defined in each user’s .hp3070 file.
<label specifier> is a string expression that can be: standard <user defined>
<label specifier> An optional string expression that selects which set of labels and functions are invoked by the function. If no <label specifier> is specified, the default value associated with the current login is used. standard invokes the default label definitions provided with your test system. Specifying any other value for <label specifier> invokes an alternate set of definitions. The default is determined by the value of the Operator.Default variable in the user’s .hp3070 file.
autofile Used when a fixture is used with more than one board type. If autofile is specified, the operator is shown a list of board types for the fixture and allowed to choose one from the list. off Cancels the operator keypad.
Example operator ! Use the default definition for <label specifier>. operator "standard" ! The operator keypad appears on the screen. ! In it are the standard label definitions. ! Selecting a label executes the function ! associated with it. operator "my_labels"; autofile ! Invokes the operator keypad with a custom ! set of label definitions. The operator ! is prompted to specify which board is being ! tested on the fixture. operator off ! Cancels the "operator" function; that is, ! the operator keypad disappearsGeneral Information
