Section 3: Instrument description
Parameter value prompting
You can use the display.inputvalue() and display.prompt() functions to create an editable
input field on the user screen at the present cursor position.
The display.inputvalue() function uses the user screen at the present cursor position. Once
the command is finished, it returns the user screen to its previous state. The display.prompt()
function creates a new edit screen and does not use the user screen.
Each of these functions can be used in the following ways:
display.inputvalue(format)
display.inputvalue(format, default)
display.inputvalue(format, default, min)
display.inputvalue(format, default, min, max)
display.prompt(format, units, help)
display.prompt(format, units, help, default)
display.prompt(format, units, help, default, min)
display.prompt(format, units, help, default, min, max)
Where:
format
default
min
max
units
help
Both the display.inputvalue() and display.prompt() functions display the editable input
field, but the display.inputvalue() function does not include the text strings for units
and help.
After one of the above functions is executed, command execution pauses and waits for the operator
to input the source level. The program continues after the operator enters the value by pressing the
navigation wheel or the ENTER key.
