DIRECTORY DO, "FILE ?.BAK" The ? is a wild card that
matches any single character in
that position. For example: FILE
1.BAK, FILE 2.BAK, FILE 3.BAK
all match the string.
DIRECTORY D1,U9,(A$) LISTS the filename stored in the
variable A$ on device number 9,
drive 1. Remember, whenever a
variable is used as a filename,
put the variable in parentheses.
NOTE: To print the DIRECTORY of the disk in drive 0, unit 8, use the
following example:
LOAD"$0",8
OPEN4,4:CMD4:LIST
PRINT#4:CLOSE4

DLOAD —Load a BASIC program from disk
DLOAD "filename" [,Ddrive number][<ON | ,>Udevice
number]
This command loads a BASIC program from disk into memory. (Use
LOAD to load programs from tape.) The program must be specified
by a filename of up to 16 characters. DLOAD defaults to device num
ber 8, drive 0.
"The DLOAD command can be used within a BASIC program to
LOAD another program on disk."
EXAMPLES:
DLOAD "BANKRECS" Searches the disk for the
program "BANKRECS" and
LOADs it.
DLOAD (A$) LOADS from disk a program
whose name is stored in the
variable A$. An error message
is given if A$ is empty.
Remember, when a variable is
used as a filename, it must be
enclosed in parentheses.
The DLOAD command can be used within a BASIC program to load
another program on disk. This is called chaining.
