@variable Description
@SENTENCE The statement that invoked the current UniBasic program in
progress. Reflects the last command entered at the ECL prompt
or in a paragraph or sentence executed by a UniBasic program.
Each UniBasic EXECUTE and CHAIN statement also resets
@SENTENCE.
@SM Inserts a subvalue mark (same as @SVM) at compile time.
For information about other delimiter variables, see “Delimiter
@variables” in this appendix.
@SVM Inserts a subvalue mark (same as @SM) at compile time.

“Delimiter @variables” in this appendix.
@SYS.BELL Enables or disables a user’s terminal bell.
@SYSTEM.RETURN.
CODE
Returns a value indicating a condition or error after the
execution of an ECL command. For most commands, 0
indicates the command was completed correctly, and -1
indicates that the command was not completed correctly.
For more information, see “@SYSTEM.RETURN.CODE
Values” in this appendix.
@TIME The time (in internal format) when the first program in the call
string program.
@TM Inserts a text mark at compile time. The text mark has no direct
effect, but can be used by UniBasic programs.
For information about other system delimiter @ variables, see
“Delimiter @variables” in this appendix.
@TRANSACTION Returns 1 if there is a transaction occurring, and returns 0 if
there is no transaction occurring.
@TTY Returns the terminal port name, such as tty01, tty1a, or console.
@UDTNO Returns an integer between 1 and the maximum number of

based on the sequence of entry into UniData. Phantom
