Parameter(s)
|
exp |
Expression to be output unconditionally to the terminal display. |
Description
This functions like the print statement, but is not affected by:
the p option used with the run command at TCL.
the printer on statement.
a heading, footing, or page statement.
All of the @() functions provided with the print statement are allowed.
When expressions are separated by commas, the next expression is output starting at the column position defined by the next output tab.
A colon at the end inhibits the output of a CR/LF following the output of the last printed line.

The line counter l displays on the screen every 50 lines.
