To display text it was as simple as:
@ row, col say "First Name:"
to draw a box:
@ top_row, top_left to bottom_row, bottom_right
there was built-in support for menus.
there were commands to save the screen to variable and then restore the screen.
main_screen = savescreen
restscreen(main_screen)
Everything was really simple. Forms were super easy. There was a command of the form:
@ row, col say "First name:" get first_name @ row+1, col say "Last name:" get last_name read
