POKE address, value
address
and value are numeric constants or numeric expressions.
address or value must evaluate to an integer in Integer BASIC.
address lies between -65535 and 65535 (-32767 and 32767 in
Integer BASIC.) value must lie between 0 and 255.
The POKE statement places the indicated value at the specified
memory address. A POKE has no effect if the address is in ROM
memory. If a POKE is not used carefully, it can disrupt the lle's
execution.
Example
10 PRINT PEEK(7900)
20 POKE 7900,37
30 PRINT PEEK(7900)
40 POKE 7900,158
50 PRINT PEEK(7900)
60 END
In
the preceding example, line 10 first displays what is currently
in memory location 7900. The value 37 is then poked into
memory on line 20. Line 30 displays the value at m~mory location
7900. The value 158 is then poked into memory and displayed in
lines 40 and 50.
