Horsepucky... here's TurboC 2.0's responce to the above input:
 
 Turbo C  Version 2.0  Copyright (c) 1987, 1988 Borland International
 t.c:
 Error t.c 6: Declaration needs type or storage class
 *** 1 errors in Compile ***
 
         Available memory 393548
 
The original poster is either blind or the variables WhatAmI, AndMoreVariables
are actually declared names (outside of the scope of the posted fragment)
such that:                              WhatAmI, AndMoreVariables;
parses as a C comma operator statement: <expr>, <expr> ;
