RENAME· FD1 :A.B • Changes file name of file "A" in floppy disk drive number
1 to filename
"B".
DELETE HA"
Deletes file "A" from disk in default drive.
CHAIN "FD1 :TEXT Chains program execution to BASIC text "TEXT B" in
BH
floppy disk. In other words, "TEXT B" is read out to
BASIC text area, and program execution contin'ues from
that heading.
The original program in the text area at this time
is made
NEW, and the content of the variable and user function is
transferred to the chained text.
It can be understood that
the function
of the CHAIN statement is as a GOTO
"filename".
SWAP" FD2:TEXT Swaps program execution to BASIC text "TEXT S-R" in
S-R " floppy disk drive number 2.
In other words, the text in execution is once shunted to the
floppy disk in the default drive, then
"TEXT S-R" is read
out to the
BASIC text area, and program execution
continues from that heading.
When the swapped program
is finished, the original text is
then read out, and the program execution continues from
the next statement after the
SWAP statement. When each
program execution
is linked, the content of the variable and
user function
is transferred. The SWAP level must not
exceed
1. In other words, SWAP instructions cannot be
made
within a swapped text.
In can be understood that the function of the
SWAP
statement is as the GOSUB "filename".
