NEW Purpose
Use the NEW command to delete the program currently stored in RAM. In
addition, all variables are set equal to ZERO; all strings and all BASIC evoked
interrupts are cleared. The free running clock, string allocation, and internal stack
pointer values are not affected. The NEW command is used to erase a program and
all variables in RAM.
Syntax
NEW
Example
>NEW
>LIST
>READY
>
NULL Purpose
Use the NULL command to determine how many NULL characters (00H) the
module outputs after a carriage return in a print statement. After initialization this
value is set to 0. Most printers contain a RAM buffer that eliminates the need to
output NULL characters after a carriage return.
Syntax
NULL[integer]
IMPORTANT
The E storage type option cannot be used if MODE is used as a
statement.
