Routine Name:
silent
Description:
Sets and returns flag which supresses certain
information
displays to console.
Usage:
silence-status = silent [silent-flag]
silent-flag 1 to suppress informative displays; 0 to
allow informative displays; 2 suppresses
startup messages.
Example:
genesis > echo { silent }
0
genesis > silent 1
echo { silent }
1
Notes:
after
Note that in the example above, the prompt is supressed
the silent flag is set to 1. Various routines use the
status of the silent flag to decide whether to print out
certain informative messages.
For
example, the routines related to element stack (pushe, pope,
stack) normally display the working element they deal with;
if silent is > 0, these routines will not echo that
information. Within any SLI control structure, the flag
behaves as if it were one greater. For example, if the
"step" command is used within a script function, the usual
message reporting the number of steps and cpu time is
supressed unless the flag is set to -1.
