Fields

UNDEFINED = 0,

The symbol record is not yet assigned a section. A value of zero indicates that a reference to an external symbol is defined elsewhere. A value of non-zero is a common symbol with a size that is specified by the value.

ABSOLUTE = 65535,

The symbol has an absolute (non-relocatable) value and is not an address.

DEBUG = 65534,

The symbol provides general type or debugging information but does not correspond to a section. Microsoft tools use this setting along with .file records (storage class FILE).
