Is any one aware of an utility (an execuatable for the MS-DOS) that works
like the FIND command in DOS, except that it also returns error codes
(to be used in batch files) corresponding to whether the string specified
was encountered or not (in a specified file)?
 
I intend to write a DOS (acually 4DOS) batch program that will prompt the
user for his/her name (or SSnumber), check to see it it exists as a line
in a (secure/hidden) file, and let the user use a part or whole of the
programs available depending upon which secure list his or her name exists
in.
 
Any pointers to utilities in the SIMTEL20 archives, and/or other shareware
sources will be much appreciated.  Since this account has recently been
acting flaky, I would apprciate your responding to me directly at 
FF76@UNTVM1.BITNET.
 
Thanks, in advance.
