another example, now I use sp1e.msb and sp2e.msb

Code:
oracle@simdes:/oracle/simp/sqlplus/mesg> echo $NLS_LANG
AMERICAN_AMERICA.WE8ISO8859P1
oracle@simdes:/oracle/simp/sqlplus/mesg> export NLS_LANG=SPANISH_SPAIN.WE8ISO8859P1
oracle@simdes:/oracle/simp/sqlplus/mesg> ls
cpye.msb  cpyus.msb  cpyus.msg  sp1e.msb  sp1us.msb  sp1us.msg  sp2e.msb  sp2us.msb  sp2us.msg
oracle@simdes:/oracle/simp/sqlplus/mesg> mkdir ../tmp
oracle@simdes:/oracle/simp/sqlplus/mesg> mv sp* ../tmp
oracle@simdes:/oracle/simp/sqlplus/mesg> sqlplus internal
Message file sp1.msb not found
Error 6 initializing SQL*Plus
oracle@simdes:/oracle/simp/sqlplus/mesg> cp ../tmp/sp1e.msb .
oracle@simdes:/oracle/simp/sqlplus/mesg> sqlplus internal
Message file sp2.msb not found
Error 7 initializing SQL*Plus
oracle@simdes:/oracle/simp/sqlplus/mesg> cp ../tmp/sp2e.msb .
oracle@simdes:/oracle/simp/sqlplus/mesg> sqlplus internal

see I get spanish messages now and instead of putting sp1us.msb and sp2us.msb it works with sp1e* that is because I changed my NLS_LANG
