字符串在masm中分成单词

Question

我正在尝试将字符串拆分为单词＆amp;检查字符串中单词的频率。

问题在于，当我尝试使用＆＃34; Space＆＃34;来分割字符串时作为分隔符，第一个单词存储在新数组中，之后字符串不会复制到下一个字符串。

这是我到目前为止所做的代码。这个程序将一个字符串作为输入并打印出该单词的出现次数。

    INCLUDE Irvine32.inc
    .data
;declaring the variables for processign 
       aString BYTE ?
       singleWords BYTE 51 DUP (?)
       indexArray BYTE 51 DUP (?)
       counterArray BYTE 51 DUP (?)
       wordIndex BYTE ?
       counterIndex BYTE ?
       mycount BYTE ?

    .code

    main PROC

; Providing offset of the aString variable where the string will be save after  ; the readString method is called

       mov  edx, OFFSET aString
       mov  ecx, 50            ;buffer size - 1
       call ReadString

; making the counter 0 for loop 
; and then passing the length of the string for processing
; wordIndex is used to save the index where the space occur to later on loop
; through that much characters in singleWords array
; counter index is just for checking the loop is working 
       mov ecx, 0
       mov esi, 0
       mov edi, 0
       mov wordIndex, 0
       mov counterIndex, 0
       mov mycount, 0

       mov ecx, eax
       Loop1:
            CMP ecx, 0 ;compare if the string is empty so stop the loop
            JE L03
            mov al, aString[esi] ;passing the characters to al for space      ;checking
            CMP al, 32
            JE L01

            mov singleWords[esi], al ; if not space then copy the character to ;singleWords array
            INC esi
            INC mycount
            INC wordIndex
            DEC ecx
            JMP Loop1
        L01:
            mov bl, wordIndex ; if sapce occur pass the index to bl
            mov indexArray[edi], bl ; save the index in indexArray
            INC edi
            INC esi
            INC mycount
            INC wordIndex
            DEC ecx
            JMP Loop1
        L03:
            mov edx,OFFSET singleWords 
            call Writestring

            movzx eax, mycount
            call WriteDec

       call Crlf
       exit
       main ENDP
    END main
