print at x,y Sets print-to-window-mode for all following print statements. To
turn off print-to-window mode (in other words, to print in message
box mode), use print at -1,0.
input$( prompt$ ) Displays an input dialog box with the given prompt.
input$(prompt$, title$) Displays an input dialog box with the given prompt and title.

input$(prompt$, title$, n) Displays an input dialog box with the given prompt and title. If n =
1, only display OK button; if n = 2, display both OK and Cancel.
val(string$) Converts a string to a number. Thus, you can read a number
entered by a user with n = val(input$(...)).
inputbox(...) Same as input$(...).
input$(1) Waits for one graffiti char or button press.
form(9,n,title$) Displays n line 2 column form. Valid values for n are 2 to 9. HotPaw
has a built-in string array s$. The first column of the form displays
the strings at the even numbered indexes of s$ as labels. That is,
s$(0), s$(2), up to s$(16) can be set with string values, and these
values are the labels displayed in the first column of the form. The
second column of the form accepts values entered by the user. Default
values for each line of the form are held in the odd numbered indexes
of s$. That is, s$(1), s$(3), up to s$(17) hold the default values
displayed in column 2 of the form. The values entered by the user
are also stored in s$(1) through s$(17). The form also has four buttons:
OK, Cancel, A, and B. The return value of the form when the user
taps a button is 1 for OK, 2 for the A button, 3 for the B button.
form(0) Returns last dialog box button status and clears the button status to 0.
