Description

  • The apex_display command can be used for menu customization, CMVC customization, TestMate test drivers and more
  • The apex_display command includes a run or execute subcommand to run a script or program and output the results to an Apex message window
  • For some scripts or programs, the apex_display output does not immediately appear in the message window, but instead appears all at once upon program completion
  • Users often prefer to see the output in real time, to monitor the progress of the script or programFor example, consider the following C-shell script cshscript.csh: 
    #!/bin/csh
    foreach xx ( 1 2 3 4 5 6 7 )
        sleep 5
        echo “Line $xx”
    end
    and an equivalent Perl script perlscript.pl: 
    my $count = 0;
while ($count < 7) {
    $count++;
    sleep 5;
    print "Line $count \n";
}
