+    and set SYSCC=0.  We take a unique "soft abort" approach - we open a macro
+    but don't close it!  This works everywhere EXCEPT inside a \%include inside
+    a macro.  For that, we recommend you use mp_include.sas to perform the
+    include, and then call \%mp_abort(mode=INCLUDE) from the source program (ie,
+    OUTSIDE of the top-parent macro).
 
 
   @param mac= to contain the name of the calling macro
   @param msg= message to be returned
   @param iftrue= supply a condition under which the macro should be executed.
+  @param errds= (work.mp_abort_errds) There is no clean way to end a process
+    within a %include called within a macro.  Furthermore, there is no way to
+    test if a macro is called within a %include.  To handle this particular
+    scenario, the %include should be switched for the mp_include.sas macro.
+    This provides an indicator that we are running a macro within a \%include
+    (`_SYSINCLUDEFILEDEVICE`) and allows us to provide a dataset with the abort
+    values (msg, mac).
+    We can then run an abort cancel FILE to stop the include running, and pass
+    the dataset back to the calling program to run a regular \%mp_abort().
+    The dataset will contain the following fields:

+/**
+  @file
+  @brief Performs a wrapped \%include
+  @details This macro wrapper is necessary if you need your included code to
+  know that it is being \%included.
+
+  If you are using %include in a regular program, you could make use of the
+  following macro variables:
+
+  @li SYSINCLUDEFILEDEVICE
+  @li SYSINCLUDEFILEDIR
+  @li SYSINCLUDEFILEFILEREF
+  @li SYSINCLUDEFILENAME
+
+  However these variables are NOT available inside a macro, as documented here:
+https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/mcrolref/n1j5tcc0n2xczyn1kg1o0606gsv9.htm
+
+  This macro can be used in place of the %include statement, and will insert
+  the following (equivalent) global variables:
+
+  @li _SYSINCLUDEFILEDEVICE
+  @li _SYSINCLUDEFILEDIR
+  @li _SYSINCLUDEFILEFILEREF
+  @li _SYSINCLUDEFILENAME
+
+  These can be used whenever testing _within a macro_.  Outside of the macro,
+  the regular automatic variables will still be available (thanks to a
+  concatenated file list in the include statement).
+
+  Example usage:
+
+      filename example temp;
+      data _null_;
+        file example;
+        put '%macro test();';
+        put '%put &=_SYSINCLUDEFILEFILEREF;';
+        put '%put &=SYSINCLUDEFILEFILEREF;';
+        put '%mend; %test()';
+        put '%put &=SYSINCLUDEFILEFILEREF;';
+      run;
+      %mp_include(example)
+
+  @param [in] fileref The fileref of the file to be included. Must be provided.
+  @param [in] prefix= (_) The prefix to apply to the global variables.
+  @param [in] opts= (SOURCE2) The options to apply to the %inc statement
+  @param [in] errds= (work.mp_abort_errds) There is no clean way to end a
+    process within a %include called within a macro.  Furthermore, there is no
+    way to test if a macro is called within a %include.  To handle this
+    particular scenario, the %mp_abort() macro will test for the existence of
+    the `_SYSINCLUDEFILEDEVICE` variable and return the outputs (msg,mac) inside
+    this dataset.
+    It will then run an abort cancel FILE to stop the include running, and pass
+    the dataset back.
+    NOTE - it is NOT possible to read this dataset as part of _this_ macro -
+    when running abort cancel FILE, ALL macros are closed, so instead it is
+    necessary to invoke "%mp_abort(mode=INCLUDE)" OUTSIDE of any macro wrappers.

+/**
+  @file
+  @brief Provides a replacement for the stpsrv_header function
+  @details The stpsrv_header is normally a built-in function, used to set the
+  headers for SAS 9 Stored Processes as documented here:
+  https://go.documentation.sas.com/doc/en/itechcdc/9.4/stpug/srvhead.htm
+
+  The purpose of this custom function is to provide a replacement when running
+  similar code as a web service against
+  [sasjs/server](https://github.com/sasjs/server).  It operates by creating a
+  text file with the headers.  The location of this text file is determined by
+  a macro variable (`sasjs_stpsrv_header_loc`) which needs to be injected into
+  each service by the calling process, eg:
+
+      %let sasjs_stpsrv_header_loc = C:/temp/some_uuid/stpsrv_header.txt;
+
+  Note - the function works by appending headers to the file.  If multiple same-
+  named headers are provided, they will all be appended - the calling process
+  needs to pick up the last one.  This will mean removing the attribute if the
+  final record has an empty value.
+
+  The function takes the following (positional) parameters:
+
+  | PARAMETER | DESCRIPTION |
+  |------------|-------------|
+  | name $  | name of the header attribute to create|
+  | value  $  | value of the header attribute|
+
+  It returns 0 if successful, or -1 if an error occured.
