Error 1084

1084: Syntax error: expecting colon before leftbrace.   

1084: Syntax error: expecting identifier before rightbrace.   

1084: Syntax error: expecting rightbrace before semicolon.   

1084: Syntax error: expecting rightparen before rightbrace.   

1084: Syntax error: expecting semicolon before rightparen.   

Possible Reasons:

1. Some typo mistake could lead to this error.
   e.g.
• for(var z:int = 0; z<items, z++)
  instead of semicolon, you put comma
• if(a==0{
  missed right parentheses before left brace

Do you know any other possible reason for this ?
