Tailoring HDSTRACE

Beginners can skip over this section.

If you want to alter some of the defaults, or always make HDSTRACE prompt for a normally defaulted parameter, you can have your own version of the interface file. To achieve this enter the following on VMS.

    $ SET DEFAULT disk:[abc.xyz]     ! Substitute the actual disk and directory
                                     ! where you keep private versions of IFLs
    $ COPY TRACE_DIR:TRACE.IFL *
    $ EDIT TRACE.IFL                 ! Make the changes you wish.
    $ DEFINE/GROUP ADAM_IFL disk:[abc.xyz] ! The /GROUP may be removed if you only
                                     ! intend to run TRACE from DCL.

SUN/115 tells you how to interpret the interface file; it describes the meanings and available options of the various keywords, and the use of the ADAM_IFL logical name. The most likely things that you would wish to alter are the values of default and vpath.

On UNIX you would do something like the following.

    % cd ~abc/xyz                    # Substitute the actual disk and directory
                                     # where you keep private versions of IFLs
    % cp $HDSTRACE_DIR/hdstrace.ifl .
    % vi trace.ifl                   # Make the changes you wish.
    % setenv ADAM_IFL ~abc/xyz:$ADAM_IFL # Append the directory to the 
                                     # interface-file search path.

SUN/144 has more details of the ADAM_IFL environmental variable.

The best way to describe the parameters is to show some examples.
