printf.txt›----------››     The printf function enables you›to print information to the screen›or any device.  It takes a variable›number of arguments.  If the first›argument is less than 255, it is›assumed to be an iocb #, and›everything is sent to that iocb. ›Otherwise the output is sent to the›screen (iocb #0).  The next argument›is the format string, followed by›any additional arguments. ›Everything in the format string will›be sent out until a % is›encountered.  The character(s)›following the % determine how the›argument is to be printed.  The›first % is for the first argument›after the format string, the second›for the second argument, and so on. ›Too few arguments will cause garbage›to be printed.  The following›characters may be used after the %:›c - print a character›d - print an integer›f - print a floating point number›s - print a string›x - print a hexadecimal number›% - print a percent sign››Note:  A character, integer, or›hexadecimal value may be obtained›from any variable defined as either›char or int.  A floating point›number is assumed to have been›defined as a 6 element char array.›     A number between the % and the›character defines the field width. ›If there aren't enough characters or›numbers in the argument, it will be›filled out with spaces.  A '-'›before the number will left justify›the field.  A decimal point and a›number will determine the decimal›part printed in a floating point›number, padded with up to 2 zeros if›there aren't enough.›     Here are some examples:›printf(">abcd<"); produces›   >abcd<›printf(">%s<","abcd"); produces  ›   >abcd<›printf(">%10s<","abcd"); produces›   >     abcd<›printf(">%-10s<","abcd"); produces›   >abcd     <›printf("%c %d %x",65,65,65);›produces›   A 65 41›››
