Hi, Can someone tell me when I should use the following functions calls? SetBitMacro() is used when writing the application info block numeric data. But I don't know why. Are there any reference to these functions? Thank you in advance. // Extract the bit at position index from bitfield. 0 is the high bit. #define BitAtPosition(pos) ((ULong)1 << (pos)) #define GetBitMacro(bitfield, index) ((bitfield) & BitAtPosition(index)) #define SetBitMacro(bitfield, index) ((bitfield) |= BitAtPosition(index)) #define RemoveBitMacro(bitfield, index) ((bitfield) &= ~BitAtPosition(index)) Elizabeth Chang ISSI Consulting Group [EMAIL PROTECTED] -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palm.com/devzone/mailinglists.html
