)
Category(ies):
Status Line
Description:
Creates a progress bar indicator in the status line. A bar will be displayed
showing relative progress between values
low
and
high
. A time-consuming
process can create a progress bar, then, through subsequent calls to
ST_progressUpdate
or
ST_progressIncrement
, indicate how much work
the process has accomplished.
Inputs:
low
— Low end of progress. A progress value of
low
displays an empty
progress bar.
high
— High end of progress. A progress value of
high
displays a solid
(filled) progress bar. Progress values between
low
and
high
display a proportionally filled progress bar.
Outputs:
pb
— Progress bar structure. This routine initializes the progress bar
structure and clears the status line indicators.
Assumptions:
None
Side Effects:
None
Availability:
On AMS 2.00 and higher.
