BASIC I/O

puts(string text)
print string, use \n for newline
---
gets(string prompt)
dialog box, use \r for newline
---
getsd(string prompt, string defaultValue)
dialog box with default, use \r for newline
---
getsi(int x, int y, int w, string defaultValue)
minidialog at x,y location and pixel width w
---
alert(string msg)
message box
---
confirm(string msg)
Confirm box - Returns 1 for Yes, 0 for No. 
---
clear()
clears the output form. 

EVENT SYSTEM

event(int blocking)
blocking=0 returns immediately, blocking=1 blocks, blocking>1 wait in 100ths of second. Events are as follows: 0:none, 1:key (character), 2:penDown, 3:penUp, 4:penMove, 5:pageUpKey, 6:pageDownKey, 7-10:hardKey1-4, 11:menuEvent. (last two need hooks)
---
key()
retrieve the character written during the last event() 
---
penx()
retrieve the x value of the pen event processed by the last call to wait, waitp, or event. 
---
peny()
retrieve the y value of the previous pen event. 
---
pstate()
returns 1 if the pen in down, 0 otherwise. 
---
bstate()
returns the state of the hard buttons. Returns 0:neither, 1:page up, -1:page down. 
---
wait()
wait for a pen or character event. Returns the character written to the graffiti area or -1 for pen event- use key() or penx()/peny() to retrieve
---
waitp()
wait for a pen event. Use penx() and peny() to retrieve the location of a pen event. 
---
getc()
wait for and return a character written to the graffiti area. 
---
hookhard(int bHook)
if bHook is nonzero, hard keys (address button, etc.) are not processed by the OS. 
---
hookmenu(int bHook)
if bHook is nonzero, menu silkscreen button is not processed by the OS. 

GRAPHICS

graph_on()
switches to the graphics form. 
---
graph_off()
switches from the graphics form to the output form. 
---
text(int x, int y, string str)
display a string str at locations (x,y). 
---
textattr(int font, int color, int underline)
set the current text drawing attributes. Available fonts are normal[0], bold[1], large[2], symbol[3], symbol11[4], symbol7[5], LED[6], Large Bold[7] (OS 3.0 only). Available colors are white[0], black[1], inverted[2]. Underline modes are none[0], solid[1], dotted[2]. 
---
textalign(char alignmentYX)
sets the alignment that text() uses. The parameter is a number between 0 and 22, where the first decimal digit describes the vertical alignment, and the second describes the horizontal. left[0], center[1], right[2]. 
---
textwidth(string str)
returns the pixel width of str
---
line(int col, int x1, int y1, int x2, int y2)
draws a line from (x1, y1) to (x2, y2) in color col. white[0], black[1], gray[2], XOR[3]. 
---
rect(int col, int x1, int y1, int x2, int y2, int radius)
draws a rectangle from (x1, y1) to (x2, y2) in color col with corners of radius radius. A radius of 0 has square edges. white[0], black[1], XOR[3]. (This function doesn't support gray) 
---
frame(int col, int x1, int y1, int x2, int y2, int radius)
same as rect() but not filled. white[0], black[1], gray[2], XOR[3]. 
---
frame2(int col, int x1, int y1, int x2, int y2, int radius, int width)
same as frame() but allows specification of width (1-3 only). 
---
title(string title)
set the graphic form title to title. 
---
clearg()
clear the graphics form. 
---
saveg()
save the graphics form internally. Returns 0 on failure, 1 otherwise. 
---
restoreg()
restore the graphics form previously saved by a call to saveg(). This can only be called once for each time saveg() is called. 
---
bitmap(int x, int y, string bits)
draw a bitmap at (x,y). The bits string is a list of hexadecimal digits in the following form: "wwxxxxxxxx..." where 'ww' is the width of the bitmap (i.e. '0a' is a 10-pixel wide bitmap), and 'xxx...' are the bits of the bitmap, each character representing 4 pixels. So, "0affc804804ffc" is a 10x4 bitmap of a rectangle ('ffc' is a solid line, '804' represents a left and right edge.)
