Too many errors. The file might not be a JScriptВ .NET file.
The code has generated too many errors. The most common cause is trying to compile a file that is not a JScriptВ .NET file. Alternatively, the code may simply have a few errors from which the compiler cannot recover, which causes many other errors.
To correct this error
Make sure the file that the compiler is compiling is a JScriptВ .NET file.
Fix the first few errors, then recompile.
