All lines that begin with a '~' are treated as control lines by the TScript language. These special control lines are:
defines a comment line; not printed or acted upon
output 'num' blank lines.
exit the script at this point. (Actually goes to label 'exit', if it exists).
prompt the user with "---MORE (*y/n)---". The script then waits for the user's response. If it is anything other than 'no' (or 'n'), the script continues. If it is a 'n' response, the script ends. (see note in '~x')
define a named label at this point in the script file, named 'label'.
query the user with the string 'prompt' and '(*y/n)'. If the user responds with anything other than 'no' (or 'n'), the query status is set to 'y' (yes). This status is used by the "~y" and "~n" control lines.
if the query status is set to 'yes' by a "~q" or "~c" control line, then goto the label line named 'label' and continue with the script. The named label can be anywhere in the script file.
if the query status is set to 'no' by a "~q" or "~c" control line, then goto the label line named 'label' and continue with the script. The named label can be anywhere in the script file.
goto the label line named 'label' and continue with the script. The named label can be anywhere in the script file.
send user 'prompt' string, get response from user, and assign the response to variable string 'num'.
assign variable string 'num' with the string 'str'. 'str' can also be any single special character sequence.
appends a string variable, 'from', to the end of another 'to'.
picks out a sub-string of a variable string 'fm' and places it in variable string 'to'. The sub-string starts at position 's' (0 is the first position). The sub- string will be 'l' characters long, maximum.
compares two variable strings (n1 & n2). This sets query status to 'y' if equal, 'n' if not, for use with the "~y" and "~n" control lines. If the optional label 'lab' is given and the two strings are equal, then goto the label 'lab'. The named label can be anywhere in the script file.
compares first 'l' characters of two variable strings (n1 & n2). This sets query status to 'y' if equal, 'n' if not, for use with the "~y" and "~n" control lines. If the optional label 'b' is given and the two strings are equal, then goto the label 'b'. The named label can be anywhere in the script file.
truncates (chops off) variable string number 'num' at position 'index' (0 is the first position). Also, 'index' can be a Text Control Sequence integer variable ("~i1").
assign i# the value 'val' (or 1, if no 'val'). The '#' is i0-i9. The 'val' is either a constant or a "~i#".
add the value 'val' (or 1, if no 'val') to i#. The '#' is i0-i9. The 'val' is either a constant or a "~i#".
subtract the value 'val' (or 1, if no 'val') from i#. The '#' is i0-i9. The 'val' is either a constant or a "~i#".
compare the value 'val' (or 1, if no 'val') to the value of i#. The '#' is i0-i9. This command sets the query status for use with the "~y" and "~n" control lines. If the optional label 'lab' is given and the query status is 'y', then goto the label 'lab'. The named label can be anywhere in the script file.
** NOTE: in any of the "~i" commands, the 'val' can be the "~p" Text Control Sequence.
gets the length of variable string 'var' and places the length in index counter number 'index'
close any open io file and then create a new io file named 'filename'. To close the current io file, give no 'filename'. The query status is set to 'y' if the file open was successful. Also, 'filename' can be one of the Text Control Sequence string variables (~0-~9).
close any open io file and then open an old io file named 'filename'. To close the current io file, give no 'filename'. The query status is set to 'y' if the file open was successful. Also, 'filename' can be one of the Text Control Sequence string variables (~0-~9).
seek to beginning of current io file.
seek to end of current io file.
seek to the position held in integer variable 'num'.
write the 'textline' to the current io file. The same special characters that apply to Text Lines apply to this 'textline', i.e. you can use the same control sequences.
read the next line in the current io file into the variable string number 'num'.
test for an end-of-file condition on the current io file. This command sets the query status for use with the "~y" and "~n" control lines. If the optional label 'lab' is given and the io file is at the end-of-file, then goto the label 'lab'. The named label can be anywhere in the script file.
uploads (sends a text file named 'filename' at this point in the script. The file MUST be ONLY ASCII text. Any control lines in the upload file will be only displayed. The script will continue, after sending the file, with the next line in the script file.
kills (deletes) a file.
delivers (mails) to 'user'. The subject of the message will be the title line of the current script. The message is sent from the MAILER-DAEMON. The content of the mail message will be the contents of the 'file'. The query status is set to 'y' if the message was successfully queued.
delivers (mails) to 'user'. The subject of the message will be the title line of the current script. The message is sent from the MAILER-DAEMON. There is a 'Reply-to:' field added to the message, with 'replyto' as the recepient. The content of the mail message will be the contents of the 'file'. The query status is set to 'y' if the message was successfully queued.
a control line beginning with '~~' is treated as a text line with a '~~' control sequence at the beginning.
a control line beginning with '~*' is treated as a request for information about 'option'. The query status is set to 'y' (yes) or 'n' (no). This status is used by the "~y" and "~n" control lines.
Options available:
- ANSI color graphics permitted
- Connect was TCP/IP type
a control line beginning with '~!' is treated as a request to change information about 'option'. The status of the option is toggled on/off.
Options available:
- ANSI color graphics permitted
begins or ends a ANSI color block. The 'status' parameter is either 'begin' or 'end'. ANSI sequences are "eaten" unless they are permitted for this user.
displays a color file, if ANSI color graphics is permitted for this user. The query status is set to 'y' (yes) or 'n' (no) depending on whether or not the user permits ANSI. This status is used by the "~y" and "~n" control lines.
changes current color set to "colorcode", if ANSI color graphics is permitted for this user.
executes the script named 'filename'. After the script is complete, control returns to the calling script. The query status is set to 'y' if the script was found.
same as ~$ above, except that the script is executed in the background, and there is no delay waiting for the script to complete.
searches string n1 for the substring n2. This sets query status to 'y' if found, 'n' if not, for use with the "~y" and "~n" control lines. The index variable 'i' is set to offset into n1 that n2 was found, or 0 if not found. If the optional label 'lb' is given and the substring is found, then goto the label 'lb'. The named label can be anywhere in the script file.
opens a connection on stream number 'n' (1-9). The connection is defined by 'cstring', which is in the form of a TNOS 'connect' or 'telnet' command. The current connection stream is NOT changed by this command. This sets query status to 'y' if the connection is made, 'n' if not, for use with the "~y" and "~n" control lines. If the connection is NOT made, the Error variable will contain the reason.
disconnects the connection on stream number 'n' (1-9). This sets query status to 'y' if the disconnect is made, 'n' if not, for use with the "~y" and "~n" control lines. If the disconnect is NOT made, the Error variable will contain the reason. If 'n' is the current stream, the stream is reset to stream 0, the user's stream.
changes the current I/O stream to that of stream 'n' (1-9). Stream 0 is the user's interactive I/O stream.
checks the state of I/O stream 'n' (1-9), and set the query status to 'y' if the connection is still valid, and 'n' if the connection is invalid or terminated.
converts string variable 'num' to upper or lower case.
executes the mSQL 'querystr' by connecting to the configured 'sql host'
* Parameters marked with an astrick (*) can be either a literal number an index counter (~i0 - ~i9), or an variable string (~0 - ~9)
