Delphi Compiler Error
E2007 Constant or type identifier expected
Reason for the Error & Solution
This error message occurs when the compiler expects a type, but finds a symbol that is neither a constant (a constant could start a subrange type), nor a type identifier.
program Produce; var c : ExceptionClass; (*ExceptionClass is a variable in System*) begin end.
Here, ExceptionClass is a variable, not a type.
program Solve; program Produce; var c : Exception; (*Exception is a type in SysUtils*) begin end.
You need to make sure you specify a type. Maybe the identifier is misspelled, or it is hidden by some other identifier, for example from another unit.
