-The ''POKE'' command stores a value into the given memory address. Both the address and the value are integers, thus the following conversions will be made:+The ''POKE'' command stores a value into the given memory address. The following type conversions are possible:
  
-- The address will be recognized as an unsigned integer, or if it's an expression, a signed integer will be converted to unsigned +  * ''address'' will be recognized as an unsigned integer 
-- The value will be truncated to 8 bits+  * if ''value'' is an integer, it will be truncated to a byte
