Sorry Henri, but I still have a question : how to have the letters in bold
type ?
Use the infont operator.  That info is a bit hidden in “2.10 Analyzing
pictures” of the MetaFun manual.

      for j=0 upto 3 :
          draw unitsquare scaled 4cm shifted (4*i*cm,4*j*cm) ;
      endfor ;
  endfor ;
  for i=0 upto 4 :
      for j=0 upto 4 :
          label.llft(
              char(i*5+j+ASCII "A") infont "SerifBold*default",
              (4*i*cm,4*j*cm)
              ) withcolor white randomized (1,1,1) ;
      endfor ;
  endfor ;

Hi Henri,
Great ! I would also like these letters to be randomly colored.
You should play with randomseed, the starting color (here white) and the
randomization amplitude (1,1,1).  You mileage may vary.

The idea is to display the first 25 letters of the alphabet. The code
below
shows the letter a to show what I want to do.
Thank you.

Use char and ASCII.

  for i=0 upto 3 :
      for j=0 upto 3 :
          draw unitsquare scaled 4cm shifted (4*i*cm,4*j*cm) ;
