# shownew(1)

a realtime display of a Modula-3 program's heap allocations

## NAME

shownew - a realtime display of a Modula-3 program's heap allocations

## DESCRIPTION

The shownew program displays a running record of the heap allocations in a Modula-3 program.

Normally, you should not start shownew directly.  Rather, the runtime will start shownew and feed it with the proper data when the argument @M3shownew=shownew is given to a Modula-3 program; for example, to run the program foo and see the allocations of that process, run foo with the argument @M3shownew=shownew.  A Trestle window will appear; when you click the start option in the control menu, the program foo will actually start.

To set the interval between updates to X seconds, add the argument @M3update=X to the commandline.  X must be an integer.
