Parameters

All but one of the parameters used by HDSTRACE are normally defaulted. If you wish to be prompted for all or some of the defaulted values give the PROMPT keyword on the command line; you can terminate the prompting by entering a $\backslash$ at any prompt and each remaining parameter will take its default value. Normally, this should not be necessary as most of the time the defaults will be satisfactory or just one or two need changing by specifying them on the command line. Prompting does have one advantage in that a ? may be entered to elicit help on that parameter.

Parameters may be given by keyword, e.g.

    $ HDSTRACE OBJECT=MYFILE NLINES=3

or by position, e.g.

    $ HDSTRACE MYFILE NO 3

where the NO is for the FULL parameter, or by a combination of both provided the positional parameters come before any keywords, e.g.

    $ HDSTRACE MYFILE NLINES=3

Full details of the parameters, their defaults and their command-line positions are given in the Appendix.
