Inter-Office Memorandum To Mesa Language Working Group Date November 23. 1977 From Wick Location Palo Alto Subject Pointers Organization SO~/SO XEROX Filed on: [MAXC]POINTERS.BRAVO DRAFT Attached is the current proposal for long pointers (Satterthwaite. Mesa Language Issues. January 28. 1977). The Language Working Group minutes and my notes show that we made the following additional points: Given the declarations b: PAGEBASE; or WORDBASE p: BASED POINTER TO T; -- or POINTER [n ..m) TO T then b[p].f is the notation proposed for (b+p).f (the add is done in software if b is of type WORDBASE). In other words. b[p] is of type LONG POINTER TO T (POINTER TO T if b is a WORD BASE)
