Tag 030 - Virtual Keyboard
Simplify supports a Virtual Keyboard message on touch screen devices. This message displays up to three lines of text together with a virtual keyboard.
Mask and UserChar subfields of API 5001 in the request control the data allowed for user input and how the data will be formatted. See under Request for more information.
If the customer presses the Enter key, any text entered on the virtual keyboard is returned in API 5001 in the Virtual Keyboard response, formatted as defined by the Mask (except no Input Mode masking).

For the following masks, the fill character is 1 (by default ’_’):
