This is my first time using C++ Builder. The code compiles, but when I attempt to run I get these error messages:

[ILINK32 Error] Error: Unresolved external '__InitVCL' referenced from C:\PROGRAM FILES\EMBARCADERO\RAD STUDIO\7.0\LIB\CP32MTI.LIB|crtlvcl
[ILINK32 Error] Error: Unresolved external '__ExitVCL' referenced from C:\PROGRAM FILES\EMBARCADERO\RAD STUDIO\7.0\LIB\CP32MTI.LIB|crtlvcl
[ILINK32 Error] Error: Unresolved external '_main' referenced from C:\PROGRAM FILES\EMBARCADERO\RAD STUDIO\7.0\LIB\C0X32.OBJ
[ILINK32 Error] Error: Unable to perform link

They seem related, but I can't figure out what they mean. Can somebody tell me what these messages mean so I can fix the problem?
Thanks.
