COPY - (BASIC 4.0 Direct Command)

The COPY direct command in BASIC 4.0 performs the same function as COPY

disk command and its format is also dependent upon application.

Use this format to copy a single file:

COPY Dsdr,"sfn" to Dddr,"dfn" ON Udn

Where sdr = the source diskette (0)

ddr = destination diskette (0)

fn = file name

Again, notice that the source (sdr) and the destination (ddr) are the same.

The CONCAT direct command is BASIC 4.0 permits the user to concatenate

files.

The format for CONCAT is:

CONCAT Dsdr,"sfn" TO Dddr,"dfn" ON Udn

The file named dfn on drive ddr will contain the contents of both dfn and sfn

after the concatenation. For example:

CONCAT D0,"YOURFILE" TO D0,"MYFILE"

This will result in MYFILE, containing the data from the old MYFILE, and

YOURFILE being concatenated. YOURFILE will remain unchanged.

The concatenation feature of COPY disk command

and CONCAT direct command are valid only for

DOS 2.

For further information regarding use of BASIC COPY and CONCAT com-

mands, refer to the Commodore BASIC 4.0 Reference Manual.

The RENAME command renames an existing file. A file can not already exist

with the file name specified in the command or the FILE EXISTS error message

will be generated.
