POKE    put byte into memory 
POKE is used to write single bytes of data into memory, and is most commonly used to pass values to and from machine 
code routines, or to save information which can be retrieved later with the PEEK command.  Two parameters are required, 
which specify the address and the value to be stored. 
Examples: 
POKE Address, Byte
POKE &4000+Pointer, GET
POKE &7000, B...

POKE$    put string into memory 
POKE$ is used to write strings into memory which can be retrieved later using PEEK$.  Two parameters are required which 
specify the start address and the string to be stored.  Each character in the string is stored in the next sequential memory 
location from the specified start address.  A Carriage Return is automatically appended to denote the end of the...

PORT    last event 
PORT is used to read the port number on which the last event happened. 
 
PORT is thus associated with the ON ... event handlers. 
 
PORT can also be part of many command lines to indicate the port number (instead of #). 
Examples: 
IF PORT=3 THEN GOSUB Password-control
PRINT PORT 2 Hello
Syntax: 
[num-var] = PORT

PRINT    send data to port 
PRINT is used to output numbers and/or strings to the output ports.  There are several major advantages over PUT and 
PUT$: 
a) PUT and PUT$ can only send a single value/character at a time. 
PRINT can send multiple characters or values. 
b)  Any output formatting required must be carried out explicitly using 
PUT and PUT$, but PRINT provides a variety of formatting...

PRINTER    enable/disable printer port 
PRINTER provides an alternative means of controlling the printer port.  The parallel printer port is only available in an Argus 
Programmable Modem, not in a T.C.Lite.  There are four forms of the command: 
PRINTER and PRINTER ON 
The PRINTER and PRINTER ON commands will enable the printer by adding 64 to the value of OPORT. 
PRINTER OFF 
This subtracts...

PROTOCOL    set file transfer protocol 
Selecting between different protocols is done by the PROTOCOL command.  Before sending or receiving using the 
SEND,X or RECEIVE,X commands you must set the right options with this command. 
 
PROTOCOL expects a number between 0 and 255.  The bits in the number are organized as follows: 
 
bit0 =0/1=  Use checksum/CRC-16 for error detection 
bit1 =0/1=...

PROTOCOL 7
 
SEND FILE4,X
: 4th and last file 
Bit5:  Ymodem-receive file name counter. 
This bit only has an effect when Ymodem-receive is selected and when bit6 is 1.  It determines how the filename is 
used when receiving multiple files with Ymodem.  If bit5 is set, then the last number in the filename is incremented.   
If bit5 is cleared, then the last number before the first dot (if...

 RECEIVE [name],B 
 DIR [name],B 
 DIR [name],F 
Exchanging data between the IB and the file is done with PEEK and POKE on addresses &2BE0 til &2BFF. 
 
When the command SEND [name],B is given, the IB of that file is placed on &2BE0. 
 
When the command RECEIVE [name],B is given, the 32 bytes on &2BE0 are placed in the IB of that file. 
 
When a new file is created with RECEIVE, the contents...

If bit7=0 the file length will not be correct, since remaining bytes in the last block are filled with 0 bytes (=NUL).  When bit7=1, 
first a CTRL-Z is placed at the end of the file, the rest is filled with 0.  This is sometimes needed when sending text files.
