OLD-SUN3CVT(1)              General Commands Manual             OLD-SUN3CVT(1)



NAME
       old-sun3cvt  -  convert  large Sun-2 system executables to Sun-3 system
       executables

SYNOPSIS
       /usr/old/sun3cvt [ oldfile [ newfile ] ]

DESCRIPTION
       Note: This program is considered to be obsolete, and will not  be  dis-
       tributed or supported in future Sun releases.

       sun3cvt  converts  an  old  Sun-2  system  program  file (predating Sun
       release 3.0) into a Sun-3 system executable file.

       The default oldfile is a.out.  The default newfile is sun3.out.

       sun3cvt attempts to create a file of  the  same  type  (magic  number).
       However,  for sharable-text files with less than 128kb of text, the new
       file will not be sharable (since Sun-3  data  segments  must  begin  on
       128kb boundaries).  Also, most programs have some text in the data seg-
       ment as a consequence of the new larger Sun-3 system page  and  segment
       sizes.

       execve(2V) executes an old Sun-2 system program file, but the program's
       text is not sharable.  Old pure-text programs with text segments larger
       than 128kb can be made sharable on machines running release 3.0 or sub-
       sequent releases by using sun3cvt.

FILES
       a.out               default oldfile
       sun3.out            default newfile
