Re: getting rid of multiple consecutive blanks ?

   It's not "one-or-two", it is just plain two, but not two-or-more.

   This next part is correct -

   Since we can't use REGEXP for this, there is no way I can fix it.   
I am emailing you two copies of your sample memo, one of which I ran  
LFdelete on once, and one twice.  On both I ran SPdelete once.

   The ColonDelete has serious problems.  I was able to make it so  
times e.g. 09:30 are preserved with a semicolon in place of the colon.  
  But, there is another problem.  Some of the text items ending in a  
colon in your sample memo have several words with spaces between them,  
such as "Other type of assignment:".  Due to the way the Pedit  
symmetric selector (ESC s) works, the work-arounds I have tried to be  
able to delete a multi-word string followed by a colon produce other  
problems.  I'm going to need to start over on this one.
