DlskeHe Drive Format
SAVE "dr;file name",dev
The SAVE statement writes a copy of the current program from
memory to the diskette in the drive specified by dr. The program is given the
name file name. dev must be present; normally, it has the value 8. If dev is
absent, a default value of 1 is assumed and the cassette is selected.
The file name assigned to the program must be new. If a file with the
same name already exists on the diskette, a syntax error is reported. How-
ever, a program file can be replaced; if an
@
sign precedes dr in the SAVE
statement text string, the program replaces the contents of a current file
namedfile name.
The diskette SAVE statement is also used primarily in immediate mode
although it can be executed out of a program.
STOP
The STOP statement causes the program to stop execution and return
control to VIC BASIC. A break message is displayed on the screen.
