Dear Aditya and =46abrice,
thanks for your responses.
I included some of =46abrice's code into mine for testing pur= pose, and indeed the multipage works now.
What is bizarre is t= hat issues appear now that didn't appear before:
  • Path A is drawn with color red on p= age 1, and in color black on all following pages, while it should stay re= d.
  • textext(<text>, <pair>) is overwriting = <text> with =22T=3D=22&decimal(currentime) which has been used = previously  in textext() before the for k=3D1 endfor loop. This over= writing happens only for the first textext() which occurs inside the for = k=3D1 endfor loop. All other textext() inside the for k=3D1 endfor loop a= re not drawn at all. If the line  =C2=AB draw textext(=22T=3D=22&= ;decimal(currentime)) scaled 2 shifted(0,2in) withcolor magenta ; =C2=BB = is commented out, the first textext() inside the for k=3D1 endfor loop is= not drawn neither. It must be an issue with textext(), because when I re= place textext() by lmt=5Foutline=5B=5D, the text is drawn.

A very similar option is to pass a variable to a= metapost drawing. This is what I use:

https://adityam.gith= ub.io/context-blog/post/metapost-animation/

It only works w= hen viewed in acrobat, you can just comment out the animation part and wr= ap it in =5CstartTEXpage .. =5CstopTEXpage to get multi-page animation.
