; /EXCLUDing a required module from an indexed library caused the
; index to never be used again. This also caused an undeserved
; [LNKLII ...] message when the index was more than one block long
; and the 2'nd or 3'rd index block was read.
; Make sure we get back to T.14 processing when we see we are not
; going to load a module, and we have an index in core.

; The TP area could never page correctly because TP.DMP left
; junk in UW.TP and LW.TP together with other incorrect calculations.
; This resulted in PAGE. UUO failures, "Ill Address in UUO", etc...
; Rework TP.DMP in LNKCOR.
;
; After fixing TP.DMP it was found that if PG.TP in lnklod needed
; to expand the window via PG.TPU, it allocated the space by expanding
; TP.AB but never read any data into the new part of the window from
; the overflow file. Fix PG.TPU to read data into the expanded window.
;
; T112P could and did allocate typechecking blocks with a link word
; containing junk left over from the last time the core was used.
; This, after a lot of twisting and turning, resulted in an undeserved
; EOF on the nnnLTP.TMP file. Fix: Initialize ABLNK after allocating
; the block.
