Welcome to OpenVMS. The method you need for this search depends on whether you want to do this from in a command, a command file (or script), or a program. I'll assume a command file. One way is to use the DCL commands OPEN, READ, and CLOSE to read each record in the file. For instance, write a command file called EOF.COM (watch out for word-wrapping): $ on error then goto exit $ open myfile 'p1' $ myrecord = " " $ doread: $ lastrecord = myrecord $ read myfile myrecord /end_of_file=done $ goto doread $ done: $ if (f$locate ("EXIT", lastrecord) .lt. f$length(lastrecord)) $ then $ ! do some processing here $ else $ write sys$error "No keyword found" $ endif $ exit: $ close myfile then execute this command file and pass it the name of the data file: $ @eof data_file.dat If you just want to check the file manually, you can use the TYPE command: $ type data_file.dat /tail=1 You should probably read the manual on the command language, DCL, at http://h71000.www7.hp.com/doc/83FINAL/9996/9996PRO.HTML It is just one manual in an extensive doc set. The HELP command is also very useful. For the "f$" functions, enter HELP LEXICAL. Hope this helps, Kelly

...or... $ search datafile.dat "EOF" /nooutput/nowarning $ if $status .eqs. "%X08D78053" then goto no_eof $ ! execute commands for a correct datafile. $ exit $ $ no_eof: $ ! execute commands indicating failing EOF test $ exit
