Readable Attributes

attr bval:CHAR;

****	The character, if the compiled program uses the same representation as the compiler.

attr source:SFILE_ID;

****	Information identifying the origin of a node in Sather source. It encodes the file and the character offset of the originating construct.

attr tp_at:$TP;

attr val:INTI;

****	The value of the char, if non-void.
