_clipboard - Copy contents from/to windows clipboard using Liquid UI Server

[Benjamin Dasari]

Purpose:
To be able to either copy data from SAPgui or user input data onto the Windows clipboard and/or retrieve data stored on the clipboard using Liquid UI scripts.
'_clipboard' is the system variable which will hold the data copied to/from clipboard.
Data could be string, multi-line text or array.

Copy TO clipboard:
If data to be saved on clipboard is from SAPgui, then the below syntax should be used:
onscreen "SAPLSPO5.0110"   
      set("R[In the clipboard]", "X");
      enter({"toclipboard":true});   // Copy contents to clipboard

If data from variable, text or array needs to be copied to clipboard, then use the below syntax:
    _clipboard = strVar;   // Copy data from string variable to clipboard
    _clipboard = txt1;     // Copy data from textbox to clipboard
   _clipboard = arrNotif;   // Copy data from array to clipboard


Retrieve FROM clipboard:
If the data that is stored in clipboard has to be retrieved, then use the below syntax:
   var strVar = _clipboard;    // Copy data from clipboard to string variable


NOTE: 
The '_clipboard' system variable is available only through the Liquid UI Server.
Feature available from Liquid UI Server version 3.5.572.0 onwards.
Feature recently added to Desktop from version 1.2.339.0 onwards, so no need to use the shell execute as specified below:
/*************************************************************************
IGNORE THIS - For Desktop, shell execute is used to copy to clipboard. Below is the link to refer to that article:
