Description

Functions and Procedures

FUNCTION GetCursor(cursorlD: INTEGER ): CursHandle;

Inside Macintosh, I-474: 

GetCursor returns a handle to the cursor having the given resource ID, reading
it from the resource file if necessary. It calls the Resource Manager function
GetResource('CURS',cursorID). If the resource can't be read, GetCursor returns NIL.

PROCEDURE NumToString(theNum: LONGINT; var theString: Str255);

Write a string representation of an integer to a string variable, without using a + sign for positive values. Defined in Inside Macintosh Chapter 18, THE BINARY-DECIMAL CONVERSION PACKAGE, I-489: "NumToString converts theNum to a string that represents its decimal value, and returns the result in theString. If the value is negative, the string begins with a minus sign; otherwise, the sign is omitted. Leading zeroes are suppressed, except that the value 0 produces '0'. For example:

theNum

theString

12

'12'

-23

'-23'

0

'0'

PROCEDURE DrawChar(ch: CHAR);

Defined in Inside Macintosh Chapter 6, QuickDraw, section QuickDraw Routines I-172 "DrawChar places the given character to the right of the pen location, with the left end of its base line at the pen's location, and advaaces the pen accordingly. If the character isn't in the font, the font's missing symbol is drawn. Note: If you're drawing a series of characters, it's faster to make one DrawString or DrawText call rather than a series of DrawChar calls."
