Thanks that works great. I got:

Code:
while ! TRUE
do
  print "enter a datafile number: "
  read DBFILE
 
  if [[ -n $DBFILE ]]
  then
  eval "
    if [[ $DBFILE = ?($NEW_FILEID) ]]
      then
      DBFILE_VALID=true
     else
       print "invalid number"
     fi
     "
  else
   DBFILE_VALID=false
  fi
done


The file numbers are generated dynamically thru sqlplus and placed into $NEW_FILEID. It all works great.

If I enter a character like !, ` , or # in response to the question "enter a datafile number?" it will stop the shell script and exit. How do I trap for those special characters?

thanks.

xmark

Xmark(1)						      General Commands Manual							  Xmark(1)

NAME

       Xmark - summarize x11perf results

SYNTAX

       Xmark datafile

DESCRIPTION

       Xmark  is  a  shell  script that reads the indicated datafile and compiles a benchmark which it writes to standard output.  It writes three
       numbers:

	      A weighted performance number for the x11perf results.

	      A weighted performance number for a standard SparcStation 1, with SunOS 4.1.2, X11R5 Xsun, and a CG3 dumb Color Frame Buffer.

	      The Xmark, which is the ratio of the two numbers above.

       The datafile must be an ordinary file, produced by x11perf in the following way:

       x11perf -display display -v1.3 -rop GXcopy GXxor -all > datafile

       It is possible to run the GXcopy and GXxor tests separately, as long as they are concatenated to the same output file:
       x11perf -display display -v1.3 -rop GXcopy -all > datafile
       x11perf -display display -v1.3 -rop GXxor -all >> datafile
       or
       x11perf -display display -v1.3 -rop GXxor -all > datafile
       x11perf -display display -v1.3 -rop GXcopy -all >> datafile

FILES

       temp.$$
	      Temporary file created in the current directory, deleted after use.

DIAGNOSTICS

       Usage: Xmark datafile
	      Xmark was invoked without arguments or with more than one argument, or with options.  Xmark takes no options.

       Error: data file does not exist or is not ordinary.
	      Xmark cannot find the datafile named on its command line, or the datafile is a special file such as a directory.

       WARNING: datafile contains nnn, not 441 or 447 'trep' results;
	      The file named on the command line does not seem to be a file generated by x11perf in the expected way.

       Diagnostic: ERROR: sum of weights =nnn, not equal to 4566.0;
	      There is an internal error in Xmark.
