Produces formatted terminal output.

 

SYNTAX

T element{, element}

 

SYNTAX ELEMENTS

element is literal text, a reference or a formatting instruction:

"text" Outputs the specified text. The text must be enclosed in double quotes.
r{;input;} Outputs the value obtained by the direct or indirect reference to a buffer or select register specified by r. An optional jQL input conversion can be applied to the value prior to output.
r{:output:} Outputs the value obtained by the direct or indirect reference to a buffer or select register specified by r. An optional jQL output conversion can be applied to the value prior to output.
(c,r) Sets the cursor to the column c and row r. Can be direct or indirect buffer references.
(c) Sets the cursor to the column c in the current row.
*cn Outputs the character c n number of times. Value n can be a direct or indirect reference to a buffer or select register.
(-n) Provides terminal independent cursor control or video effects.
+ Outputs carriage return/line feed at the end of the output line. On ROS emulations, this clause will inhibit the carriage return/line feed at the end of the output line.
B Sounds terminal bell.
C Clears the screen (outputs top-of-form).
D One second delay. Often used when outputting error messages.
Ir Converts the integer r (0 to 255) into its equivalent ASCII character. r can be a direct or indirect reference to a buffer or select register that contains the integer.
L Terminates a loop started with a T element. The elements between the T and L are executed three times.
Sn Outputs the number of spaces specified by n. The value n can be a direct or indirect reference to a buffer or select register than contains the number of spaces.
T Marks the top of a loop. The loop is terminated by the L element. The elements between T and L are executed three times.
U Moves the cursor up one line.
Xr Converts the hex value r (x"00" to x"FF") into its equivalent ASCII character. The value r can be a direct or indirect reference to a buffer or select register that contains the hex value.

 

NOTES

The T command must be followed by a single space and each element must be separated by a comma. Continuation lines (which do not start with a T) can be created by ending the preceding line with a comma.

 

TERMINAL INDEPENDENT CURSOR CONTROL

Terminal independent cursor control is available using the same table of negative numbers as used by the jBC @ command. See the jBC @ command for more details.
