I have added two new statements
PEEK(address) returns the content of memory cell at address
POKE(address, value) write value in memory cell at address
PEEK and POKE mainly help playing with the registers.
Added a scrolling buffer which ease displaying DIR and LIST screen by screen.
Work in progress
Currently, I am working on adding file manipulation inside BASIC programs.
I plan to add statements like open, read, write (binary and text)
