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