Advantage:
- Zero replacement parameters are no longer written before the function is called.
- Limit to 9 optional parameters
In the previous format function, you could get the stack address from the first value parameter and thus get the following parameters directly from the stack (also works with C compiler)
Passing the stack address to a subfunction is not possible. So first take over the parameters and then call the subfunction.

; Syntax:
;
; %[flags][width][.precision]specifier
;
; Flags:
; - Left-justify within the given field width; Right justification is the default
; + Forces to preceed the result with a plus or minus sign (+ or -) even for positive numbers
; '[char] Fill Character; Space is the default
;
; With:
; [Number] Minimum number of characters To be printed. If the value To be printed is shorter than this number, the result is padded With blank spaces
; The value is not truncated even if the result is larger.
;
; Precision:
; [Number] For float and Double specifiers: this is the number of digits to be printed after the decimal point
; For string specifiers: truncate string
; For hexnumber: defined input value; 2 = byte, 4 = word; 8 = dword; 16 = qword
;
; Specifier:
; b Byte
; a Unsigned byte
; w Word
; u Unsigned word
; l Long
; q Quat
; i Integer
; f Float
; d Double
; X Hex; Uppercase character
; x Hex; Lowercase character
; s String
; c Char; value as integer
;
; Control Character;
; \\ Backslash (\)
; \n Line Feed
; \r Carriage Return
; \t Horizontal Tab
; \v Vertical Tab
; \' Double Quote (")
