Category  Native procedure  
Format  (text obj)  
Parameters 


Description  text formats obj in
humanreadable format and prints it as graphic text to the graphic
screen. Printing uses the graphics state
*gstate*
for starting coordinates, font, colors and drawing mode.
The current point in *gstate* is not updated. See here for details on the graphic state. The return value is #n to avoid trashing the graphics.

Category  Primitive procedure  
Format  (ticks? obj)  
Parameters 


Description  ticks? returns #t for a "ticks" value and #f for any other object.

Category  Native procedure  
Format  (tickspersec)  
Parameters  None  
Description  tickspersec returns the number of ticks in a second (typically 100, but don't take this value for granted!). Always use this function to scale the results from ticks measuring functions.

Category  Native procedure  
Format  (tickssince ticks)  
Parameters 


Description  tickssince returns the number of ticks elapsed since ticks. Ticks are the smallest measurable units of time in PalmOS. There are (tickspersec) ticks in a second.

Parameters 


Description  time? returns #t for a time value and #f for any other object.

Category  Native procedure  
Format  (timehour time)  
Parameters 


Description  timehour returns the hour part of a time value as an integer value in the range 0..23. Note that PalmOS time values don't include seconds, so there is no timesecond function.

Category  Native procedure  
Format  (timeminute time)  
Parameters 


Description  timeminute returns the minute part of a time value as an integer value in the range 0..59. Note that PalmOS time values don't include seconds, so there is no timesecond function.

Category  UI event 
Format  (timeout) 
Parameters  None 
Description  timeout is the event posted when the maximum
waiting time for an event has passed and no other event has arrived
yet. The waiting time can be specified in a call to
frmpopup or
frmgoto. The PalmOS API documentation calls this event nilEvent, but I think this name is unfortunate in a Lispish context :) 
Category  Primitive procedure (MathLib required)  
Format  (truncate num)  
Parameters 


Description  truncate converts num to a floating point number and returns the integer part of it. The result is not a LispMe integer, it's a floating point value.

Category  Native procedure  
Format  (ts>date ts)  
Parameters 


Description  ts>date returns the date part of a timestamp value as a date value (foreign value).

Examples 

Category  Native procedure  
Format  (ts>number ts)  
Parameters 


Description  ts>number returns the seconds part of a timestamp value as an integer. This is the number of seconds elapsed since January 1st 1904, midnight.

Category  Native procedure  
Format  (ts>time ts)  
Parameters 


Description  ts>time returns the time part of a timestamp value as a time value (foreign value). Note that a PalmOS time value doesn't include seconds, so you may have to use ts>second to achieve precision to a second.

Category  Native procedure  
Format  (tssecond ts)  
Parameters 


Description  tssecond returns the seconds part of a timestamp value as an integer value in the range 0..59. To extract other parts of a timestamp, use ts>date and ts>time and the corresponding extraction functions for date and time.
