This article was previously published under Q30416



SYMPTOMS
In the Microsoft Macro Assembler (MASM) version 5.1, only the first LOCAL variable on a line generates CodeView information. Attempting to put a watch on a LOCAL variable that is not the first LOCAL variable on a line will cause Codeview to display the following message box:

 |             ERROR             | |        Unknown Symbol         | | Press Any Key to Continue... |



RESOLUTION
To avoid the problem in MASM version 5.1, break up any lines that define more than one LOCAL variable into multiple lines.



STATUS
Microsoft has confirmed this to be a problem in MASM version 5.1. This problem was corrected in MASM version 5.1a.



MORE INFORMATION
The following sample code can be used to demonstrate the problem:

Sample Code
; Assemble options needed: /Zi
 * Link options needed:    /CO

.MODEL small, C   ; A Language specifier is required when using ; the LOCAL directive in MASM 5.1, 5.1A and ; when using QuickAssembler 2.01 and 2.51. ; MASM 6.0 does not require this.

.CODE

Start:

call procedure    ; Call the procedure mov  ax, 4C00h    ; Exit int  21h

procedure proc

local    first:word local    second:word,third:word

; To avoid the problem in MASM 5.1, break the preceding line up   ; into multiple lines: ;   ; local      second:word ; local     third:word

ret

procedure endp

.STACK

END Start
