Thanks, this works great,  although at first it was complaining
because it took spurious braces as part of file name : 


%   PAGES =         \{6\},
\makeatletter
  PAGES =         \{ \@@input \mjmbasename.last_page \},
  %PAGES =         \{ \@@input /home/documents/latex/proj/\mjmbasename/\mjmbasename.last_page \},
  %PAGES =         \{ \@@input{/home/documents/latex/proj/\mjmbasename/\mjmbasename.last_page}\},
\makeatother

and then in the pdf, 

YEAR = {2020},
AUTHOR1EMAIL = {marchywka at hotmail.com},
AUTHOR1ID = {orcid.org/0000-0001-9237-455X},
PAGES = { 28 },
CONTACT = {marchywka at hotmail.com},
