INFLD is a powerful and flexible field-level input and display routine, operating in both text and GUI modes. In GUI mode, it takes on the form of a edit control, combo box, date/time picker, or up/down (spinner) control, depending on the parameter options. INFLD's GUI mode is generally application-compatible with text mode, but of course requires either A-Shell/Windows or ATE. INFLD is also used internally to implement the A-Shell dot-prompt, the VUE command line, and INMEMO.
History/compatibility note: Originally developed as an upward-compatible replacement for the native AMOS subroutine INPUT.SBR, INFLD was sold as a standalone product under AMOS. The A-Shell implementation is upward compatible with the AMOS version, but adds many additional capabilities, most notably the GUI extensions.
