# replayheap(1)

replay a recorded Modula-3 heap activity

## NAME

replayheap - replay a recorded Modula-3 heap activity

## SYNTAX

**replayheap \[-showheap pgm\]** file

## DESCRIPTION

The **replayheap** program replays the recorded trace of the heap activity of a Modula-3  program contained in file.

Typically, the trace is recorded by running the Modula-3 program of interest with the option @M3showheap=recordheap.  This leaves the trace in the file m3heap.trace, which can then be replayed with the command replayheap m3heap.trace

When **replayheap** starts, it creates a window with buttons.  Each button corresponds to some event in the heap activity trace.  Clicking a button will replay all the events until the next occurrence of the event.

## OPTIONS

- **-showheap** *pgm*

  Use *pgm* instead as *showheap* to display the heap.

## SEE ALSO

[showheap(1)](/showheap/1.md) [recordheap(1)](/recordheap/1.md)
