I received a question: In text input, how do you display the keyboard screen as soon as the user clicks a field? I investigated how to do it after dividing it into two actions: "bring the cursor in a field" and "displaying the soft keyboard". First, I was interested in "displaying the soft keyboard". I searched the keyword "KeyBoard" in the API reference, and found the two API functions: SysKeyboardDialog SysKeyboardDialogV10 These should be prepared to display the keyboard, but SysKeyBoardDialog needs to pass parameters, so I just ignored it and decided to use SysKeyboardDialogV10 which doesn't require a parameter or return a value. API functions like this normally work from NS Basic very easily. Then, after putting a command button on the screen, I set the following line:         SysTrapSub 179,0 Compile ... Run ... Start the keyboard after moving the cursor to an input area. Because the cursor was not in the field, the error was shown... I thought it looked all right despite the error, so I tried again after setting the cursor.                  Yes. If the cursor is in the field, tapping the "KEYBOARD" button brings up the soft keyboard. Next, "bring the cursor in a field". I made a wrong judgment here:         NS Basic should have "SetFocus" command. With this assumption, I looked though the handbook, and found this:         Cursor Id moves the cursor to the specified object But I couldn't find details; the handbook didn't provide it. So I tried specifying the field's ID number like:         Cursor Id 1005 But this is an error. How about this:         Cursor Id,1005 This is an error, too. Next,         Cursor Id Fld1005 Error. Maybe I am doing something totally wrong. Finally this one:         Cursor Id "Fld1005" It goes through. So the combination of two lines:         Cursor Id "Fld1005"         SysTrapSub 179,0 This works fine. I was satisfied after finding how to use the Cursor Id command, but with some curiosity I checked the NS Basic's message board. Mmm... I found a message "don't understand CURSOR ID". The person seemed to try the same thing. But I also found a response to the message:         You'd better use the SetFocus method instead of the Cursor ID command .... I checked the handbook again. My mistake :-)         Fld1005.SetFocus         SysTrapSub 179,0 Yes. This works.
