CONNECT    connect to remote modem 
CONNECT is identical to the modem command O (ATO).  The modem will take the line, wait for an incoming carrier and try 
to connect to it.  The connection will only be established, when the configuration of the relevant S-registers matches the 
remote carrier. 
 
The ON CONNECT event can be used to detect a successful connection.  This can also be determined...

COPY    copy files 
This command is used to copy one file on the disk to another file.  The new file is identical to the original one.  Using 
wildcards (* or ?) is not possible. 
Examples: 
COPY MYPROG , MYPROG.BAK
COPY MYPROG TO MYPROG.BAK
Syntax: 
COPY (FILE|!) [string] (TO|,) (FILE|!) [string]

CTS    Clear To Send 
CTS is one of the hardware handshaking signals defined in the RS232 standard, and each serial port on the modem is 
capable of controlling a CTS signal as an output. 
 
CTS is a signal provided by modems and other DCEs, to inform the terminal (DTE) that it is ready to accept data for 
transmission.  It is used in conjunction with another signal, RTS (Ready To Send) as part...

DATA    define constant data 
The DATA command is used to store numeric and string constants within a program.  Such values may be read one or more 
times using the READ command. 
 
DATA commands may appear anywhere in the program, but must be the first and only command appearing on a line.  As 
many data items as will fit on a line may be included, with individual data items being separated by...

DATE$    read system date 
DATE$ is used to read the date from the internal clock/calendar, and format it into a text string in the form DD-MM-YY.  
When I wrote this text on the 23rd of July 1990, PRINT DATE$ reported 23-07-90. 
 
The date can also be obtained in integer format by using the individual functions DAY, DDAY, MONTH and YEAR. 
 
DATE$ can also be used to change the system date....

DAY    read/set day of week 
DAY is used to read or set the day of week on the internal clock/calendar. 
 
When reading it returns an integer from 1 to 7, day 1 being Sunday.  Similarly, when setting the day of week, the day number 
from 1 to 7 must be specified.  An incorrect value will cause the current setting to remain unchanged. 
Examples: 
DAY=5
IF DAY=1 THEN Day$=Sunday
PRINT DAY

DCD    Data Carrier Detect 
DCD is the RS232 signal used by modems to indicate that a connection has been established with a remote system.  It is 
activated by the modem when a connection occurs, and is normally used as an output from the modem.  However within the 
BASIC environment, it can also be used to read the connect status of modem port #3. 
 
With port #1 or #2 the DCD command is used...

DDAY    read/set day in month 
DDAY is used to read or set the day within the month for the internal clock/calendar.  When reading it returns an integer from 
1 to 31.  Similarly when setting, the day number from 1 to 31 must be specified; an incorrect value will cause the current 
setting to remain unchanged. 
Examples: 
DDAY=15
IF (DDAY=1 OR DDAY=21 OR DDAY=31) Suffix=st
PRINT DDAY

DELETE / DEL    delete program lines/files 
The DELETE command, in its various forms, is used to delete lines from a program and to delete files from the disk filing 
system. 
Deleting program lines 
DELETE may be followed by two line numbers which define the range of lines to be removed.  The command: 
DELETE 50,100 or DELETE 50 TO 100
will remove all program lines from 50 to 100 (inclusive)....
