If a block has been assigned a character value in the Value on Selection window, the _getValue method causes a program halt. Use the _getText method to return the value of a block that has a character value.

Example

If the value 4 was assigned to the block in the Value on Selection window, _getValue returns the value 4 and assigns it to the variable VALUE:

   call notify('block1','_get_value_',value);
   if (value=4) then
      _msg_='You have made reservations for four.';
