# s command (FlashBASIC Debugger)

The s command displays the contents
of the subroutine stack.

## Syntax

```
{flash.routine.name:}s{!}
```

## Description

The ! lists
the actual lines of source where the gosub statements
are found (FlashBASIC only).

Note: *flash.routine.name* can only be specified if the program has been optimized through
the FlashBASIC compiler. When *flash.routine.name* is specified, the corresponding debugger command
is executed against the specified routine. The colon separating *flash.routine.name* and the debugger command
is required.
