DISK BASIC
This
command
finds
all
occurrences of
a reserved
word
or other
string
literal
in
the resident
program.
The
"
finds"
are listed
on
the display as five-digit line
numbers.
To
search
for
any basic
reserved
word
(including reserved arithmetic operators),
use the
keyword
as-is.
To
search
for
anything
else
(including variable-names and
text),
enclose the text inside quotes.
For example, suppose
you
have
the
following program
in
memory:
10
PRINT "THIS
IS A
TEST"
20
INPUT "PRESS
<EIMTER>
FOR THE NEXT PRINT MESSAGE";
Z$
30
A = A

t
PRINT

all

except
for
cases
where

part
of
a
quoted
string: lines
10 and
40.
CMD
"X"
*
"PRINT"
will find
all
occurrences of
"print"
as
a string
literal:
line
20.
CMD

list
line
30, but
CMD
"X%
"
+ " will
list
line
40.
CMD
"X"
*
"A"
will
list
lines 10, 20,
and
30.
Notice
that
variables
and

both
treated
as string
literals.

This
command
enables or disables dual video/printer output.
While
the function
is
"on,"
all
video output
is
copied
to the printer,
and
all
printer output
is
copied
to
the video. (The
printer
must be
on-line
when
you
turn dual output
"on.")
Video and
printer output
may
differ
due
to intrinsic
differences
in the printer
and
video
devices.
Examples
CMD
"Z"
»
"ON"
Turns dual
video/printer
output
on.
