call后面接字符串解决办法

    include    user32.inc
    includelib user32.lib
    include    kernel32.inc
    includelib kernel32.lib
    
    .data
    szTitle        db    'title',0
    szText        db    'my name is',0
    
    
    .code
    
    
start:    
    call    loc1
    db    'hey man',0
    invoke    MessageBox, NULL, addr szTitle, addr szText, MB_OK  ;不会到这一句，为什么？
    
loc1:    
    pop    esi
    push    esi
    invoke    MessageBox, NULL, esi, esi, MB_OK
    ret
    
    end start
