Compiler enhancement (edit 711): new auto-defined macro COMPILER_VERSION equates to the compiler edit. This can be used in ++IF conditions to avoid or warn about code that is requires a newer version of the compiler. For example:
++IF COMPILER_VERSION >= 710
TYPEDEF BOOLEAN I,2
++ENDIF
Unfortunately, since the macro was introduced in edit 711, an attempt to reference it's value in a prior version will generate a "conditional expression not constant" error, so that will only be useful going forward. However, you can use ++IFDEF to test if it's defined—and if not, you will know that it is prior to version 711.
