POKE - DualBrain/bsharp GitHub Wiki
To write (poke) a byte of data into a memory location.
a and b are integer expressions.
The integer expression a is the offset address of the memory location to be poked. The DEF SEG statement last executed determines the address. BASIC does not check any offsets that are specified.
The integer expression b is the data to be poked.
b must be within the range of 0 to 255. a must be within the range of 0 to 65535.
The complementary function to
POKE is PEEK. The argument to PEEK is an address from which a byte is to be read.
POKE and PEEK are useful for efficient data storage, loading assembly language subroutines, and for passing arguments and results to and from assembly language subroutines.
20 POKE &H5A00, &HFF
Places the decimal value 255 (&HFF) into the hex offset location (23040 decimal). See PEEK function example.
