SQLPLUS within UNIX script problem

I have a command that looks like the following in a unix shell script log=`sqlplus -s $DW_USER_at_$ORACLE_SID @$SCRDIR/$4 << + $PSWD
+`

When I look a the output in $log I not only see the result set but also every file in that directory. Almost seems like echo * is happening somewhere along the line. Anyone know how I can get around this ?

Thanks
