IV | Input Variable | |
| Value: | N/A |
| Units: | N/A |
Range:
min=the minimum range value (optional); max=the maximum range value (optional)
Allows operator input of variable information under program control. It is usually used with the message command (MS) to prompt for operator input of the variable specified in the IV statement. The cursor is placed at character position “i”. The program waits until a number is entered before continuing execution. You are not allowed to type past the end of either display line. Variables store 4 digits to the right of the decimal place.
When minimum and/or maximum range values are specified, the IV command will not accept inputs outside this range (one of the following messages is displayed on the keypad):
SInput below minimum, Press ESC to resume
SInput above maximum, Press ESC to resume
Variables can be used in a math equation, conditional expression or to set any command parameters (Example: DA, DC, VE, AC, LP, IF, TD, etc.). A variable can be used anywhere in a program a real number or integer is used. Use care when performing math on variables used in LP statements. LP will truncate the

MS1,“” | Clears the Display |
MS1,“How many?: ” | Writes string beginning at character 1, top line |
IV12,(PIECES),1,15 | Waits at 12th character for the # of pieces in the range |
MS1,“” | Clears the Display |
MS1,“How long?: ” | Writes string beginning at character 1, top line |
IV12,(LENGTH) | Waits at 12th character for the # of pieces. |
LP(PIECES) | Loops the number of pieces entered |
DI(LENGTH) | Defines the desired move length/distance. |
GO | Moves the length commanded |
