MenuPick (Create Selectable Menu Options)

The MenuPick instruction is used to create a list of selectable options that can be used when editing a MenuItem value.

Syntax

Example

Example #1

The following program demonstrates the use of the custom menu functionality in the datalogger. The custom menu is named DataView; it will appear as the main menu in the datalogger. DataView has three submenus (PanelTemps, TCTemps, and the System menu) and one menu item (Counter) on the first level menu. Counter has a pick list of 4 values. Each submenu is displaying two values from the program. DisplayValue in the first submenu is displaying a value from a data table. All of the other values, which use MenuItem, are displaying current measurement values.

This program was written for aCR6, but other dataloggers can use similar code for custom menus (voltage ranges, channel numbers, or other parameters may need to be changed to reflect the specifications of the datalogger).

Example #2

This example demonstrates how to create a custom menu to edit values in a Constant table, using MenuItem and MenuPick.

NOTE: If using MenuPick to change values in a constant table, the constant must be in the constant table and the constant name must be the first parameter in MenuPick.

Public ApplyandRestart as Boolean

ConstTable
  Const A = 0
  Const B = 1
  Const C = "Hello"
  Const D = "World"
EndConstTable

DisplayMenu("Config",-3)
  MenuItem ("A-Pick",A)'Create pick list for Constant A
  MenuPick(A,0,5,10,15,20,30)
  MenuItem ("B-Free",B)'Free form entry for Constant B
  MenuPick(B)
  MenuItem("C-Pick",C)'Create pick list for Constant C
  MenuPick(C,One,Two,Three)
  MenuItem ("D-Pick",D)'Free form entry for Constant D
  MenuPick(D)
  MenuRecompile("ApplyAndRestart",ApplyAndRestart)
  MenuPick(TRUE,FALSE)
EndMenu

BeginProg
  Scan (1,Sec,3,0)
  NextScan
EndProg

Remarks

If a pick list of options is desired for a MenuItem, the MenuPick instruction must immediately follow the MenuItem for which the list is being generated. Each item in the list is separated by a comma. The pick list is limited to a total of 512 characters. The Items in the pick list must be constants.

MenuPick can also be used to create a custom menu item with a pick list for changing values in a constant table. To change the value of a constant in a constant table, the constant must be in the constant table and the constant name must be the first parameter in MenuPick (see example program 2). Refer to MenuRecompile for additional information.

Parameter

MenuPick Item

Enter the items to be used for the pick list for a MenuItem. Each item is separated by a comma. The pick list is limited to a total of 512 characters.
