| SysvarTags | Type (Enumeration)

estack.h

enum SysvarTags {...};

An enumeration to describe types of system variable entries on the expression stack.

If the tag of an entry on the expression stack is EXT_SYSTEM_TAG (0x1C), then the byte below it is the tag of a TI-Basic system variable. SysvarTags is enumerated type for describing such extended entries (see top_estack for more info about how entries on the expression stack are organized). This enum is quite big, and here is a complete list of system variables tags defined in it (all values are in hex), with their meaning:
