title: Syntax errors in my assembly code
body: <p>I had this code and I was wondering if anyone would be willing to help me get it working.</p>
  
  <pre><code>TITLE MASM Template                     (main.asm)
  
  ; Description: this code is supposed to print out each letter followed by a space and then the capitalized version on seperate lines
  ; Revision date:
  
  INCLUDE Irvine32.inc
  .data
  
  myArray byte 'l','s','d','t','h','c','f','u','c','k'    ;my array of 10 characters
  .code
  main PROC
  
      mov ecx,0                                        ;clears ecx
      mov ecx,LENGTHOF myArray                         ;should be 10
      mov edi,OFFSET myArray                   ;will point to the beginning of the array
      mov eax,0                                       ;clears eax

  LOne:
  
      mov eax,myArray[esi]          ;points the pointer at the beginning of myArray
      WriteChar eax                     ;prints the designated value in the array
      WriteChar 32                    ;prints a space (32 is the ascii value for ' ')
      sub eax,32                      ;subtracts 32 from the ascii value of the char
                           ;the capital version of each letter is -32 of its ascii value
      WriteChar eax           ;prints the capital version
      call CLRF               ;prints new line
      inc esi                 ;increments esi to the next array value
      dec ecx                 ;decrements ecx, moving it through the array
  
      loop LOne               ;loops back until ecx is equal to zero
  
      exit
  main ENDP
  
  END main

  <p>It won't compile giving me syntax errors.</p>
