## Macros

#define | PO_DEFAULT 0
| no parse options set by default
#define | PO_FREE_OPTIONS (PO_ALLOW_BARE_REFS|PO_ASSUME_LOCAL|PO_STRICT_BOOLEAN_EVAL)
| mask of options that have no effect on code access or code safety
#define | PO_IN_MODULE (1LL << 33)
| do not use directly, this is set automatically in user module programs
