The NComm V3.0 script language
==============================
A scriptfile is an ASCII textfile that consists of different commands,
separated by one or more linefeeds. Edit the scriptfiles with your
favourite editor. Only one command is allowed per line, but blank
lines are also OK. A line can consist of blanks before the command and
between parameters. Comments can be added by entering a semicolon. A
label is marked with a colon as its last character, e.g. "quit:". The
script commands are case independent, but strings within quotes are
not.
Scripts are mainly used to automate logons, or to companion you while
you are online. Scripts can also perform more advanced functions,
like grabbing mail and perhaps posting it on another board (or even
printing it!). You set the limits...
NComm scripts can be started from the menu or from the phonebook (at
CONNECT). You may also Shift-Select a script when starting NComm.
One example script and one Host-Mode script have been included with
the NComm package. Take a look at them if you don't understand how to
use the commands.
Important: The filenames specified in a scriptfile are relative to
the current directory, NOT the default upload and download
directories!

Summary of Script commands
--------------------------
ASCSEND
Starts ASCII text send of the filename given. Example:
ASCSEND "df1:text/msg"
The TIMEOUT command also concerns ASCSEND. If ASCSEND is halted by a
^S and no ^Q has been received within the timelimit specified by
TIMEOUT, the script will go on with the next command. XON will be
turned on before ASCSEND.
----------------------------------------------------------------------
AUTODOWN
Turns Zmodem auto-download ON or OFF.
Example:
AUTODOWN ON ;Turns Zmodem auto-download on
AUTODOWN OFF ;Turns Zmodem auto-download off
----------------------------------------------------------------------
AUTOUP
Turns Zmodem auto-upload ON or OFF.
Example:
AUTOUP ON ;Turns Zmodem auto-upload on
AUTOUP OFF ;Turns Zmodem auto-upload off
----------------------------------------------------------------------
AUTOXFER
Turns G&R commands ON or OFF.
Example:
AUTOXFER ON ;Turns G&R commands on
AUTOXFER OFF ;Turns G&R commands off
----------------------------------------------------------------------
BEEP
Will cause an audible 'beep' of the terminal and / or will flash the
screen and / or will bring the screen to front, depending on what you
have configured in the SCREEN menu. Nothing is sent through the
serial port.
----------------------------------------------------------------------
BREAK
Sends a break to the host machine. Equivalent to SEND "\l".
----------------------------------------------------------------------
CAPTURE
Toggles ASCII capture on/off. Examples:
CAPTURE "filename"
Will open the capture file and turn on capture. It will be opened in
'append mode' if the file exists...
CAPTURE SUS
Will suspend capture. Capture can be turned on again with the command
CAPTURE ON
CAPTURE OFF
Will turn capture off and close the file. The file cannot be opened
again with the CAPTURE ON command.
----------------------------------------------------------------------
CD
Problems occur when the "CD" command is used with the CLI function.
The "CD" command has therefore been made a special function. It
simply changes the directory that is to be used for commands started
with the "CLI" function.
Example:
CD "RAM:" ;Will change the current working directory to 'RAM:'
----------------------------------------------------------------------
CHAIN
Will start a new script. The control will never return to the calling
script. This is useful when you need extremely long scripts that
won't fit in memory.
Example:
CHAIN "NComm:ReadNews.script"
Note: Variables will not be deleted when using the CHAIN command.
Use the command CLEARVARS if you want to delete all variables.
----------------------------------------------------------------------
CLEARVARS
This command deletes all variables.
----------------------------------------------------------------------
CLI
Will execute a program or a command. The output from these programs
and commands will occur in the NComm window. This command will be
relative to the directory you were standing in when you started NComm.
Please note; Current Directory can not be set with the CLI command,
probably due to problems with the Amiga operating system. The "CD"
function must therefore be used for this purpose.
Examples:
CLI "dir dh0:comms"
CLI "type ram:foo.bar"
CLI "pkax ram:grabfile.arc"
----------------------------------------------------------------------
CLRSTACK
This command clears the RETURN stack, i.e. it forgets active
subroutine calls (gosubs). The command is handy at error situations,
when you wish to "jump out" of the program and start over again, for
example in conjunction with TIMEOUT or WHEN commands.
----------------------------------------------------------------------
CONFIG
Will read a new configuration file. Example:
CONFIG "NComm:MBBS.config"
----------------------------------------------------------------------
CONVERSE
Will wait for a prompt from the host machine and answer it.
Examples:
CONVERSE "Enter your name:" "Name\n" ;Waits for 'Enter your name:'
CONVERSE "enter your password:" "\p\n" ;Sends phonebook password + CR
CONVERSE "Command:" "G\n" ;Sends 'G' and newline
----------------------------------------------------------------------
DELAY
The script program will take a break. The program will function as
normal.
Examples:
DELAY 5 ;Wait 5 seconds
DELAY UNTIL 12:00 ;Wait until 12 o'clock.
----------------------------------------------------------------------
DIAL
Will dial one or more phonenumbers. Can also dial entries in the
phonebook. If you choose to dial phonenumbers, use the command
'DIAL#'. The numbers must be placed within quotation marks. If you
choose to dial more than one number, the numbers can be separated by a
comma.
Examples:
DIAL# "454143"
DIAL# "380949", "416588", "454143"
Named entries in the phonebook can be dialled by specifying the
boardname within quotation marks. You only have to specify the number
of letters required to separate the board from the others. The
name is not case sensitive.
Examples:
DIAL "AmigaBBS"
DIAL "rode", "Mike's", "media"
DIAL "Rodeløkka (M)BBS"
----------------------------------------------------------------------
DLWHEN
Deletes the last defined WHEN command. Repeated usage will succesive
delete the "previous" WHEN command. See: WHEN.
----------------------------------------------------------------------
DORX
This command executes an ARexx command/script.
Example: DORX "ncomm:test_rx.ncomm"
----------------------------------------------------------------------
DOWNLOAD
Will download a file from the host machine. The protocol specified in
the TRANSFER menu will be used as long as nothing else is specified.
If you want to specify another protocol, enter a comma and a letter.
The filename is "dummy" when using Zmodem.
X == Xmodem, Y == Ymodem, B == Ymodem-B, G == Ymodem-G, Z == Zmodem,
K == Kermit, E == External XPR (as defined in config file),
I == Bimodem, P == BModem Plus, J == Jmodem, Q == QuickB,
V == VMS, U == Uue-Ascii
Examples:
DOWNLOAD "df1:junk" ;Will use the default protocol
DOWNLOAD "df0:trash",X ;Will always use Xmodem
----------------------------------------------------------------------
DTENTHS
This is a much more precise delay command, but only use this command
when this accuracy is needed, since it will lock up the system. The
DTENTHS parameter is the number of tenth seconds to wait.
Examples:
DTENTHS 2 ;Wait 0.2 seconds
DTENTHS 16 ;Wait 1.6 seconds
----------------------------------------------------------------------
DUMP
Command for debugging a script. It dumps a list of all variables and
what they contain, on screen. If you specify a filename, output will
be appended to the file instead, and will not be shown on screen.
Example: DUMP "t:debug_info"
----------------------------------------------------------------------
DWHENS
Deletes a specific WHEN command. It should be followed by the string
that you used for activating the WHEN command.
Example:
WHEN "abc" GOTO abc
WHEN "bcd" GOTO bcd
[...]
DWHEN "abc" ;remove "abc" when checking
----------------------------------------------------------------------
DWHENS
Will disable all previously used WHEN commands. See: WHEN.
----------------------------------------------------------------------
ECHO
This command defines if characters read by the INPUT command shall be
echoed. ECHO ON should be used when input is read from a user in the
other end. ECHO OFF should be used when input is read from a Bulletin
Board System, or when the user is not supposed to see what he writes.
ECHO should be turned ON if the functions ASCSEND and MSGSEND are
supposed to echo text locally. The output from the CLI command will
be sent to the serial port if ECHO has been turned on.
----------------------------------------------------------------------
END
Will stop the execution of the script. This command is especially
useful in front of subroutines.
Example:
WHEN "Read>" GOSUB next
WAIT "No more unread."
END
Next: SEND "\n"
MESSAGE "(Skipping to next unread)\n"
RETURN
----------------------------------------------------------------------
GOSUB
Will call a named subroutine. Useful when you want to use the same
command many times within a script, or in connection with WHEN or
TIMEOUT. The subroutine is ended with 'RETURN', and the control is
passed to the line following the GOSUB afterwards.
Example:
GOSUB myRoutine
END
MyRoutine: MESSAGE "Fooo\n"
BEEP
RETURN
----------------------------------------------------------------------
GOTO
Ever heard of this? Will jump to a named place in the script.
Example:
GOTO quit
...
quit: CAPTURE OFF
HANGUP
END
Numeric example that counts from 1 to 100:
SET $sum="0"
SUM: SET $sum = $sum+"1"#
MESSAGE "Number: "$sum"\n"
IF !$sum == "100" THEN GOTO SUM
NOTE: Don't use "LABEL: GOTO LABEL" if you want an "endless" wait.
This will steal most of your machine's CPU. Use the DELAY or WAIT
commands instead.
----------------------------------------------------------------------
HANGUP
Will send the hangup string to the modem (or lower DTR if you have
selected DTR hangup).
----------------------------------------------------------------------
IF <expression> THEN <operation>
It should be obvious what this command does. A valid expression can
be either a comparison of two strings or a check for a file. The
exclamation mark ('!') works as a boolean 'NOT' operator.
String comparisons are performed with the "==" operator, which tests for
case independent equality, i.e. "foo" == "FOO" is TRUE;
!"bar" == "yum" is TRUE (because of the '!' (NOT) operator)
EXISTS checks if a file exists. The following are examples on valid
IF commands:
SELECTFALSE opens up a "Yes / No" requester and is TRUE if the user
selected "No".
RING checks for a (hardware) RING signal.
CARRIER checks for (hardware) CARRIER detect.
IF $password == "abcdef" THEN MESSAGE "Access granted\n"
IF !$password == "xyz" THEN GOTO KillUser
IF EXISTS "NComm:host.config" THEN CONFIG "NComm:host.config"
IF !EXISTS $file THEN SEND "File not found!\n"
IF !SELECTFALSE "Slow modem?" THEN SET $baud = "300"
Loop: DELAY 1
IF RING THEN GOSUB Send_ATA
IF CARRIER THEN GOTO Connect
GOTO Loop
The whole command must be placed on a single line, including the 'THEN'
part...
SEE ALSO: SET
----------------------------------------------------------------------
INPUT
This command reads input from the serial port and places it in a
variable until a specific string has been received. ^H (backspace)
deletes the last character, ^U deletes the whole string. The
searchstring will not be added to the variable. Control characters
will not be added. Example:
SEND "Enter your first name: "
INPUT $name "\r" ;Input will be placed in the variable 'name'
;until carriage return is received.
The TIMEOUT command also concerns the INPUT command. The timeout
defines how long INPUT shall wait for the terminating string ("\r" in
the mentioned example). Example:
TIMEOUT 180 Goto BiBi
SEND "Enter a command: "
INPUT $cmd "\r"
...
BiBi: SEND "\n\nLooks like you fell asleep!! Bye-bye!\n"
HANGUP
END
It is also possible to read a single character without having to
wait for ENTER or other strings:
INPUT $char ""
INPUT can both be used for reading input from a user in connection
with "Host Mode", or grabbing pieces of text from a Bulletin Board
System;
WAIT "Bulletins have been updated: "
INPUT $bull " "
----------------------------------------------------------------------
LOADKEYS
Will read a new macrokeys file.
Example:
LOADKEYS "NComm:dec.Keys"
----------------------------------------------------------------------
LOADPHONE
Will read a new phonebook file.
Example:
LOADPHONE "NComm:dialdir.phone"
----------------------------------------------------------------------
MENUSELECT
This command selects a function from the menu.
Example:
MENUSELECT SYSTEM 0 ;Open About Window
MENUSELECT TRANSFER 6 2 ;Selects KERMIT Change Directory
----------------------------------------------------------------------
MESSAGE
Will write a message on the screen. Nothing is sent through the
serial port. You may use all the conventions that are valid for
macrokeys. Please refer to the NComm.doc.
Example:
MESSAGE "\fReading mail...\n"
MESSAGE "Storing mail in file \"DF1:Mail.txt\"\n"
SET $var = 5
MESSAGE "1"+$var-"2"#"\n" ;The result will be 4 ((1+5)-2)
----------------------------------------------------------------------
MSGSEND
Same as the "message send" function in the TRANSFER menu, will upload
a message.
Example:
MSGSEND "DF1:tekst/msg"
----------------------------------------------------------------------
NCOMMTOFRONT
Brings the current NComm screen to front.
Example:
NCOMMTOFRONT
----------------------------------------------------------------------
PADLINES
Turns padding of blank lines ON or OFF.
Example:
PADLINES ON ;Will turn on padding of blank lines
PADLINES OFF ;Will turn off padding of blank lines
----------------------------------------------------------------------
PALETTE
Will open the palette requester.
----------------------------------------------------------------------
PRINTER
Turns the printer ON or OFF.
Example:
PRINTER ON ;Will turn on the printer
PRINTER OFF ;Will turn off the printer
----------------------------------------------------------------------
QUIT
Exits NComm.
----------------------------------------------------------------------
READVAR
This command reads a line from the file defined by VARFILE and places
the input in the variable name that follows. Please refer to VARFILE.
The variable will contain "EOF" after the read if the function hits an
end of file mark...
----------------------------------------------------------------------
REDIAL
Turns redial ON or OFF.
Example:
REDIAL ON ;Will turn redial on
REDIAL OFF ;Will turn redial off
----------------------------------------------------------------------
REPEAT<->UNTIL <expression> ...
This command performs what is situated between REPEAT and UNTIL. If
the expression is FALSE/TRUE, the procedure will be repeated. See
"IF...THEN" for a discussion of valid expressions. The command has the
same restrictions as WHILE/ENDWHILE.
Example:
REPEAT
SEND "Enter command: "
INPUT $cmd "\r"
GOSUB DoCommand
UNTIL $cmd == "quit"
Numeric example that counts from 1 to 100:
REPEAT
SET $sum = $sum+"1"#
MESSAGE "Number: "$sum"\n"
UNTIL $sum == "100"
----------------------------------------------------------------------
REQUEST
This function is used when the scriptfile is run without human
presence. It will then be unpreferable that AmigaDOS puts up a
requester if problems occur (disk full, read / write error etc.) By
turning request OFF, this is disabled. Note: NComm will automatically
overwrite existing files if request has been turned off
Example:
REQUEST OFF ;Turns requesters off
REQUEST ON ;Will turn the requesters back on again
----------------------------------------------------------------------
RESUME
Turns Zmodem resume ON or OFF.
Example:
RESUME ON ;Turns Zmodem resume on
RESUME OFF ;Turns Zmodem resume off
----------------------------------------------------------------------
RETURN
Returns from a subroutine. See GOSUB.
----------------------------------------------------------------------
SEND
Sends a string to the host machine. You may use all the conventions
that are valid for macrokeys. Please refer to the NComm.doc
Examples:
SEND "\n" ;Linefeed
SEND "Read\n" ;'Read' plus a CR
SEND "\m1^z" ;Macro #1 plus a 'Control-Z'
SEND "\p\n" ;The password stored in the phonebook plus a CR
----------------------------------------------------------------------
SET
This command is used for assigning values to variables. Variables
have name in the form $name where 'name' starts with a letter. The
value must be of type string, either a literal (with quotation marks)
or another variable. A number is assigned to a variable by entering
the number as a string.
Examples:
SET $name = "Daniel"
SEND $name
SET $filename = "RAM:foo"
CAPTURE $filename
SET $UserName = $name
SET $Number1 = "13"
SET $Number2 = "5"
SET $Sum = $Number1+$Number2# ; Set Sum = Number1 + Number2 (18)
SET $Sum = $Sum+"1"# ; Set Sum = Sum + 1
MESSAGE $Sum"\n" ; Output the result (19)
The last example needs a bit of explanation. NComm threats string and
numeric variables exactly the same way. The only difference is when
you want to do some sort of calculation.
To specify that this line should perform a calculation, place a '#'
character after the arithmetic expression. You may add strings or
string variables after the arithmetic expression if necessary:
MESSAGE "1"+"1"#"\n" ; Outputs '2' plus a linefeed.
Numbers always have priority from left to right. The following
result will therefore be (1+5)*2 == 12, not 1+(5*2) == 11:
SET $var = "1"+"5"*"2"#
MESSAGE $var"\n"
Negative variables are also accepted:
SET $sum ="-1"+"-3"#"\n" ; The result is -4
The following arithmetic types are supported:
'+': Addition '/': Division
'-': Subtraction '%': Modulo
'*': Multiplication '^': Power
Variables can be used everywhere where strings are expected. There
are a few pre-defined variables available:
$date contains the current date and time (READ ONLY).
$ncomm contains the current version number (READ ONLY).
$baud contains the current baud rate (Read/Write).
$length contains the current data length (Read/Write).
$parity contains the current parity (Read/Write).
$stopbits contains the current number of stopbits (Read/Write)
$charset contains the current character set (Read/Write).
$filereq opens up a filereq and returns the filename (READ ONLY).
$stringreq opens up a textreq and returns the string (READ ONLY).
$rand gives you a random number between 0 and 65535 (READ ONLY).
$boardname contains the current board name (READ ONLY).
$boardnum contains the current board phone number (READ ONLY).
$logtime contains the current logon time (READ ONLY).
$dldir contains the current download dir (READ ONLY).
$uldir contains the current upload dir (READ ONLY).
Example that generates a random number between 0 and 15:
set $range = "15" ;Generate a random number between 0 and 15
;Actual result will be placed in the $newrand variable
main:
gosub rand
message "Your lucky number is: "$newrand"\n"
end
rand: ;To generate a new random number, gosub to this routine
set $newrange = $range+"1"#
set $newrand = $rand*$newrange/"65536"#
return
It is also possible to concatenate several variables and/or literals;
SEND $name"\n"
SET $directory = "NComm:files/"
INPUT $filename "\r"
UPLOAD $directory$filename
SET $baud = "300" ;sets baud-rate to 300 baud
SEND $date"\n" ;print current date and time
SET $length = "7" ;7 data bits
SET $parity = "E" ;even parity
SET $charset = "IBN" ;set IBN character set
SET $var1 = "10"
SET $var2 = "10"
SET $var3 = $var1+$var2/"4"# ; Set $Var3 = ((10 + 10) / 4) == 5
MESSAGE $var3+"5"#"\n" ; Display with linefeed: $Var3 + 5 == 10
It is not valid referring to variables having no value assigned.
NOTE: You may use the pre-defined variable $FILEREQ for obtaining
a filename.
Example:
SET $filename = $FILEREQ ;open filereq, put name in $filename
IF $filename != "" CONFIG $filename ;use the filename
Use the pre-defined variable $STRINGREQ if you want the user to
type in a string.
Example:
SET $baud = $STRINGREQ ;set baud-rate to number entered by user
----------------------------------------------------------------------
SIMPLEREQ
Use this command if you want to display text in a seperate requester.
Example: SIMPLEREQ "You selected: "$filename"\n"
----------------------------------------------------------------------
STRLEN
This function returns the length of a string.
Example: SET $foobar = "foobar"
STRLEN $len $foobar
MESSAGE $len"\n"
This example will output 6. You may also specify the text directly
like this: STRLEN $len "foobar"
----------------------------------------------------------------------
STRPART
This function copies parts of a string, starting at a specific position,
into another string.
Example:
SET $varin = "foobar"
STRPART $varout 3 2 $varin
MESSAGE $varout"\n"
This example will output the string "ba" (startpos 3, length 2).
----------------------------------------------------------------------
TIMEOUT
This command lets you configure how long NComm should wait in a WAIT,
CONVERSE or INPUT command. Default timeout is 'forever', but this is
not preferable if the script is running without human assistance. If
the host machine does not answer, it is reasonable to believe that it
has hung, and a scriptfile should then automatically disconnect from
the system. The TIMEOUT command can be used in many ways.
Examples:
TIMEOUT 10
Means that NComm shall wait a maximum of 10 seconds. If no text has
been received within the timelimit, NComm will go on with the next
command.
TIMEOUT 10 SEND "\n"
Specifies that NComm is to wait a maximum of 10 seconds for each WAIT
or CONVERSE command. If the specified text has not been received
within 10 seconds, NComm will send a linefeed to the host machine and
will continue waiting for the text. NComm will continue sending
linefeeds every 10th second until the host machine has answered.
TIMEOUT 0
NComm is to go back to the default mode, i.e. wait forever.
Example of typical usage:
TIMEOUT 30 GOTO quit
CONVERSE "Enter your name:" "Daniel Bloch\n"
CONVERSE "Enter your password:" "gruff\n"
CONVERSE "Command:" "GRAB\n"
...
...
END
quit: MESSAGE "\n\nThe board has hung, call the SysOp!!!\n"
BEEP
HANGUP ;Hang up so that we won't get a shock when
END ;the next phonebill arrives!
----------------------------------------------------------------------
UPLOAD
Uploads a file to the host machine. See the 'DOWNLOAD' function for
the correct syntax.
----------------------------------------------------------------------
VARFILE
This command opens a file for input. The file may later on be used
for reading text into variables via the command READVAR.
Example:
VARFILE "ncomm:host/users/"$user ;open input file for reading
READVAR $passwd ;place first line of file in variable $passwd
READVAR $laston ;place second line of file in variable $laston
VARFILE CLOSE ;closes the input file
MESSAGE "Hello "$user"! You were last on at "$laston"\n"
----------------------------------------------------------------------
WAIT
Waits for a special text to be received. Will wait forever if the
TIMEOUT command has not been used.
Examples:
WAIT "" ;Wait for 'anything'
WAIT "\n" ;Wait for a linefeed
WAIT "Command:" ;Wait for 'Command:'
----------------------------------------------------------------------
WHILE <expression> DO ... ENDWHILE
This function performs what is situated within DO and ENDWHILE until
the expression is TRUE/FALSE.
Example:
SET $cmd = ""
WHILE !$cmd == "quit" DO
SEND "Enter command: "
INPUT $cmd "\r"
GOSUB DoCommand
ENDWHILE
Numeric example that counts from 1 to 100:
SET $sum="0"
WHILE !$sum == "100" DO
SET $sum = $sum+"1"#
MESSAGE "Number: "$sum"\n"
ENDWHILE
It is not valid jumping out of a WHILE/ENDWHILE loop using GOTO or
RETURN. It is still possible to exit the loop using GOTO and the
command CLRSTACK.
----------------------------------------------------------------------
WHEN
Defines what to do when a special text is received. The command is
case sensitive.
Typical example:
WHEN "--more--" SEND " "
This command will make NComm send a 'blank' line every time it
receives the 'more' prompt from the host machine. This is independent
of where in the script you reside. It is possible to specify up to
twenty such textstrings.
Example:
WHEN "--more--" SEND " "
WHEN "NO CARRIER" END
WHEN "Sysop is coming online!" GOSUB ShutUp
WHEN "No more unread" GOTO Quit
Loop: CONVERSE "Command:" "\n"
GOTO loop
Quit: SEND "G;Y\n"
END
ShutUp: SEND "I'm not at home! You are chatting with a scriptfile!\n"
SEND "Send BIBI at the speed of light!!!\n\n"
RETURN
----------------------------------------------------------------------
WRITE
This command writes a textstring to a file. If the file exists, the
string will be appended to the file. Example:
WRITE "NComm:host/log" "Logged in: "$username"\n"
| |
Name of file String
----------------------------------------------------------------------
