The CPU is in a 64-bit ARM environment, such as DCCIOSARM64.EXE.ĭefined in code that may be shared with the macOS compiler and another compiler on another platform such as Linux that does not have a rigid stack alignment requirement.

The following standard conditional symbols are defined:įor a list of compiler versions, see Compiler Versions.įor Delphi Alexandria, compiler version. Conditional symbols must start with a letter, followed by any combination of letters, digits, and underscores they can be of any length, but only the first 255 characters are significant.

Use the must be found within the same source file.

You can define a conditional in the following ways: Any valid conditional symbol is treated as false until it has been defined.

2 Using Conditional Defines for the Compiler VersionĬonditional symbols work like Boolean variables: they are either defined (True) or undefined (False).
