Remarks
(cont.)
• units is a string that indicates the units (e.g., “V” or “A”) for the value and help
provides a message prompt on the bottom line.
• Along with specifying the format for the input field, there are options to specify
minimum and maximum limits for the input field. When NOT using the “+” sign for the
value field, the minimum limit cannot be set to less than zero. When using the “+”
sign, the minimum limit can set to less than zero (e.g., -2).
• There is also an option to specify a default value. When this command is executed,
the initially displayed value for the field will be the
default value.
• Message prompts to instruct the operator should be displayed prior to calling this
function. Make sure to position the cursor where the edit field should appear.
• The input value is limited to ±1e37.
• After sending this command, script execution holds 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.
