Reformat C comments for new indentation level

//Some of this macro code was originally written with the help of a slickedit
//employee back in the days of visual slick edit for windows (i.e. versions 1-3
//or so). I don't recall who it was. This macro was written before slickedit
//reformatted comments as I typed them and I still use it when I re-indent code.

//The purpose of this macro is to reflow a comment at a new indentation level or
//to just reformat the comment per the document width of 80 using a tab indent
//setting of 4.

//To use this macro you select the comment using line mode making sure your
//cursor is at the new indentation location. Then execute the macro. The comment
//will be reformatted to the new width with the C/C++ "/*" " *" and "*/" to
//open/close the comment.

//Some improvements would be to obtain the document width and tab indent
//settings programatically. In addition, the comment style could be obtained and
//used (this is fixed for the old C style comment format).

_command reflow_c_comment() name_info(','EDITORCTL_ARG2|MARK_ARG2|MACRO_ARG2)
   if (!select_active()) {
      message('There needs to be an active selection');
      return (0);

   if (lowcase(_select_type('')):!='line') {


   //Determine the column of the opening of the comment.  This will be
   //used to indent the new comment.


   //Need to replace / * and * / before we replace the * otherwise
   //replacing the * will get rid of the / * and * / and cause problems
   replace('/\*','','PNIrm*');     //Get rid of '/*' in the line
   replace('\*/','','PNIrm*');     //Get rid of '*/' in the line
   replace('\*','','PNIrm*');      //Get rid of '*' in the line
   parse old_p_margins with left_ma right_ma para;
//set the margins to reformat the comment with the text not going past column
//80 and leaving room for my tab indent of 4. We will reformat the text in
//columns 1..n and then will re-indent the text later.
   p_margins=1' '81-new_left_ma+1-4' 'para;


   //Create the spacesstring which will be used to indent the newly formatted
   stringcounter = 1;
   while (stringcounter < new_left_ma)
   spacesstring = spacesstring' ';

   filter_put_string(spacesstring'/* 'text);
   while (p_line+1<line) {
      filter_put_string(spacesstring' * 'text);
   insert_line(spacesstring' */');
