Summary
Compiler symbol for detecting compiler capabilities.
Pascal
{$IFDEF SYMBOL}
// The compiler feature is available
{$ENDIF SYMBOL}
Description
Once jedi.inc is included at the top of your pascal source file, the following compiler symbols are defined depending on your compiler and IDE version.
These symbols can be used for conditional compilation based on compiler available features:
