This version of NEC2 runs on PC-386/486. It is compiled with
32-bit Lahey Fortran. It requires only about 2.4 MByte memory
to run (DOS or WINDOWS)

========================================================
The Lahey compiler required the following changes to the NEC2D
FORTRAN source from the netcom ftp-site:

1) IRESRV decreased from 4M to 100k on line 23, set to 2 (as dummy) in
   rest of file. This influences memory requirement at start-up:
      IRESRV=100k ==>   requires about 2.5 MByte
      IRESRV=275k ==>   requires about 5.2 MByte
      IRESRV=4M   ==>   requires about 65 MByte
2) Commented out line 91, uncommented line 90:
    OPEN (UNIT=2,FILE=INFILE,STATUS='OLD',ACTION='READ',ERR=702)
3) Changed TYPE to PRINT on line 3175:
    PRINT 1,MSG(IND+2:MSGLEN)
4) Customized cpu-time routine SECONDS on line 8182:
C     LAHEY ON PC:
      CALL TIMER(ITICKS)
      CPUSECS = ITICKS/100      
      RETURN
      END
========================================================

To compile with Lahey one should use:

  F77L3 nec2d.for /Q1 /No /NS
  386LINK nec2d -nozui -pack -lib vaxibm3
  CFIG386 nec2d -nosignon

For a stand-alone executable (linked-in DOS-extender) which in
addition uses disk virtual memory the link-command should be:

  386LINK nec2d -nozui -pack -lib vaxibm3 -stub runb vmmb

This has no effect under Windows (DPMI overtakes Lahey vmm) but it
should work under DOS.
