Syntax  

pascal <data-definition/function-definition> ;
_pascal <data-definition/function-definition> ;
__pascal <data-definition/function-definition> ;

Description 

Use the pascal, _pascal, and __pascal keywords to declare a variable or a function using a Pascal-style naming convention (the name is in uppercase). 

In addition, pascal declares Delphi language-style parameter-passing conventions when applied to a function header (parameters pushed left to right; the called function cleans up the stack). 

In C++ programs, functions declared with the pascal modifier are still mangled.
