Integer arrays take up two-fifths the space of floating-point arrays
(e.g., DIM A% (100) requires 209 bytes; DIM A (100) requires 512
bytes.)
NOTE: Array elements are numbered from zero up to the number
given in the DIM statement.
More than one array can be dimensioned in a DIM statement by sep
arating the array variable name by commas. If the program executes
a DIM statement for any array more than once, the message
"RE'DIMed ARRAY ERROR" is posted. It is good programming prac
tice to place DIM statements near the beginning of the program.
EXAMPLE:
10 DIM A$(40),B7(15),CC%(4,4,4)
Dimensions three arrays, where arrays AH, B7, and CC% have,
respectively, 41 elements, 16 elements and 125 elements
—Display the contents of the disk directory on the screen
DIRECTORY [Ddrive number]!,<ON |,) Udevice][,wildcard]
The F3 function key in C128 mode displays the DIRECTORY for
device number 8, drive 0. Use CONTROL S or NO SCROLL to pause
the display; any key restarts the display after a pause. Use the COM
MODORE key to slow down the display. The DIRECTORY command
cannot be used to print a hard copy. The disk directory must be
loaded (LOAD"$",8) destroying the program currently in memory in
order to print a hard copy. The default device number is 8, and the
default drive number is 0. See also CATALOG.
EXAMPLES:
DIRECTORY
DIRECTORY D1, U9, "WORK"
DIRECTORY "AB*"
Lists all files on the disk in unit
8.
Lists the file named "work," on
drive 1 of unit 9.
Lists all files starting with the
letters "AB" like ABOVE,
ABOARD, etc. on all drives of
unit 8. The asterisk specifies a
wild card, where all files starting
with "AB" are displayed.
