Format
Function
LOAD or LOAD " filename"
This command loads
the specified BASIC text file or a machine language file to be
linked with a BASIC program from cassette tape.
(See pages 14 and
20.)
Only
BASIC text files and machine language programs can be loaded with this
command. When the file to be loaded
is a BASIC text file, the current program is
cleared from the BASIC text area when the new program is loaded.
Note When loading a machine language routine
to be linked with a BASIC program, the
LIMIT statement must
be executed to reserve a machine language progam area
in memory.
Further, the applicable machine language program file is executed as
soon as loading is completed if the loading address is inside that area. (In this case,
the BASIC text is not erased.)
The
LOAD command can be used within a program to load a machine language
program file.
