Supposing, you now the memory layout of the VIC20 (which I don't):
10 FOR i=mem_start TO mem_end
20 POKE i,0:IF PEEK(i)<>0 THEN ?"Can't clear memory location ";i
30 POKE i,255:IF PEEK(i)<>255 THEN ?"Can't set memory location ";i
40 POKE i,85:IF PEEK(i)<>85 THEN ?"Pattern 0x55 failed on memory location";i
50 POKE i,170:IF PEEK(i)<>170 THEN ?"Pattern 0xaa failed on memory location";i
60 NEXT i
where mem_start and mem_end are the appropriate values for the memory area
to test.

(Hell, I really had to think how to do the not-equal comparison and append
a variable to a string in BASIC... Haven't used that language for years
now :)
