Overview

PC (Pascal Compiler)

• Add {$u-} and {$u+} compiler flags. The "U" option defaults to {$u+} and this will list uncompiled code. If set off {$u-} then uncompiled code (due to conditional compilation) will not be listed.
• Redundant loading of the A0 register reduced. For instance, in many cases making assignments using fields within a record will not calculate the record address for each assignment.
• Add {$w-} and {$w+} compiler flags. the "W" option defaults to {$w+} which forces fields longer than one byte to be word aligned, relative to the start of the record. {$w-} will not force word alignment. Note that you must use caution if the software is for a 68000 system, since access to those fields will likely cause an address error unless you access those fields a byte at a time.
• Fix array indexing in the case where the array is greater than 32K bytes but larger than 65K bytes.
• Various synonyms added to make translation back and forth with Turbo Pascal easier. Note that extreme care must be used when dealing with loop exits and function/procedure returns, since Borland used the "wrong" names for these.
  

  Standard	Optional Identifier
  <<	shl
  >>	shr
  hex	word
  longreal	double
  real	single
  record	object
  longinteger	longint
  shortinteger	shortint

• Records may inherit their initial fields from a previously defined record. For instance, in the defintions :
  

  abc = record
    def : integer ;
    ghi : longinteger
  end ;
  jkl = record (abc)
    mno : real
  end ;
  

  Record type jkl contains the fields def, ghi, and mno. Note that no fields in the record being inherited (the parent record) may be procedures, function, or records. This restriction can normally be gotten around by using a "deferred reference" :
  

  pq = record
    rs : procedure  (i : integer)
  end ;
  tu = record (pq)
    vw : real
  end ;
  

  Is not valid, but if you define :

  trs = procedure (i : integer) ;
  pq = record
    rs : trs
  end ;
  tu = record (pq)
    vw : real
  end ;
  

  Then it will be compile, and is identical in function.

DB (Host Debugger)

• Multi-byte variables on odd addresses can now be accessed if running on a 68020/68030 system.
• The trap handler for the user program is no longer loaded using F$Vmodul, this has proven to be very unreliable on new systems, especially those with memory management. The trap handler is written to a pipe, and then loaded from that pipe.

SE (Screen Editor)

• Less likely to crash when given strange files to read. Non printable characters in input file are shown as a period ".".
