Remarks
(cont.)
• After sending this command, script execution holds up and waits for the operator to
enter a value and press ENTER:
• If limits are used, the operator will not be able to input values outside the
minimum and maximum limits.
• For positive and negative entry (“+” sign used for the value field and/or the
exponent field), polarity of a non-zero value or exponent can be toggled by
positioning the cursor on the polarity sign and turning the wheel. Polarity will also
toggle when using the wheel to decrease or increase the value or exponent past
zero. A zero value or exponent (e.g. +00) is always positive and cannot be
toggled to negative polarity.
• After sending this command and pressing the EXIT key, value will return nil.
Details See “Parameter value prompting” on Section 14.

Example Displays an editable field (“+0.50”) for operator input – Valid input range is -0.10 to
+2.00, with a default of 0.50:
display.clear()
value = display.inputvalue("+0.00", 0.5, -0.1, 2.0)
display.loadmenu.add
Function Adds an entry to the “USER TESTS” submenu of the “LOAD TEST” menu.
Usage There are two ways to use this function:
display.loadmenu.add(displayname, chunk)
display.loadmenu.add(displayname, chunk, memory)
displayname Name to display in the menu.
chunk Chunk is the code to be executed.
memory Save or don’t save chunk and displayname in non-volatile
memory.
Set memory to one of the following values:
0 or display.DONT_SAVE
1 or display.SAVE
The default memory setting is display.SAVE.
Remarks
• This function adds an entry to the “USER TESTS” submenu of the “LOAD TEST”
menu. If the given item is subsequently selected via the front panel, the
chunk will
be executed when the RUN key is pressed.
• The chunk can be made up of scripts, functions, variables and commands. With
memory set to display.SAVE, commands are saved with the chunk in non-volatile
memory. Scripts, functions and variables used in the chunk are not saved by
display.SAVE. Functions and variables need to be saved along with the script (see
“
Saving a user script” page 14-13). If the script is not saved in non-volatile memory,
it will be lost when the Series 2600 is turned off. See Example 1 below.
• It does not matter what order the menu items are added. They will be displayed in
alphabetical order when the “USER TESTS” menu is selected.
