/DEBUG[=(option[,...])]
       /NODEBUG (default)

    Positional qualifier.

    Traces certain operations by placing the DSR commands in the
    output file. You can specify the following options:

    o  ALL

       Specifies all five options (CONDITIONALS, CONTENTS, FILES,
       INDEX, and SAVE_RESTORE).

    o  CONDITIONALS

       Causes DSR to ignore all conditional processing commands (.IF,
       .IFNOT, .ELSE, .ENDIF) in the input file. DSR includes both
       true and false conditional information in the output file
       along with formatted text. For further details on the .IF,
       .IFNOT, .ELSE, .ENDIF, and .VARIABLE commands and the /VARIANT
       qualifier, enter HELP DSR at the DCL prompt.

    o  CONTENTS

       Causes DSR to output all .SEND TOC commands along with the
       text being sent to the table of contents.

    o  FILES

       Causes DSR to output all .REQUIRE commands as well as the text
       of the require files.

    o  INDEX

       Causes DSR to output the indexing commands, .INDEX and .ENTRY,
       in addition to the text to which they refer.

    o  SAVE_RESTORE

       Causes DSR to output all .SAVE and .RESTORE commands.

    If you specify only one option, you can omit the parentheses.
    If you specify /DEBUG without specifying any options, ALL is
    assumed.
