UASM32 Unicode SIZEOF-LENGTHOF Bug

[LiaoMi]

Hi,

all text lines are defined with the same size after assembly

        .686                                      ; create 32 bit code

  A2WDAT MACRO quoted@@text,dataname:VARARG

;; ------------------------------------------------------

;;     ASCII literal string to UNICODE "dw" conversion.
;;     The macro has the ASCII character range 0 - 255
;;     and will convert 1 byte characters in the quoted
;;     string to 2 byte UNICODE characters written as "dw"
;;     in the initialised data section.
;;     The final string length is dictated by the MASM line
;;     length limit and is set at 240 characters.
;;
;;     This MACRO is primarily designed to be called by
;;     other macros, it does not create a .DATA section
;;     and it does not terminate the string data it writes.
;;
;;     This characteristic is so the macro can be called
;;     repeatedly by another macro. The calling macro
;;     then terminates the string when it has no more
;;     to write.
;;
;;     The optional dataname label is designed to be used
;;     on the first call and ommitted on subsequent calls
;;     when adding text to the original label address.
;;
;;     You can write a .DATA section entry in this manner.

Hello,
The executable show nothing on my screen.
Can you explain a little what is the problem?.

Hi TouEnMasm,

thanks, you are absolutely right, this topic has already been discussed here  - http://masm32.com/board/index.php?topic=2054.msg29625#msg29625

This just recall me for what i have created the CANS and CUNI macro who works in 32 and 64 bits.
The CUNI macro create dw instead of byte and is shorter and more readable than the WSTR.
the CUNI_ANS is here to switch easily between UNICODE and ANSI with just the UNICODE constant defined.

SDK does not seem to have these macros?

I will add them as soon as possible.           Later:DONE
