I would like to add a new command to an existing environment. The `\renewenvironment`

command does not help a lot since I need to copy and paste the entire environment definition.

For an example I would like to make a `\FORALL_P`

for the `algorithmic`

environment such that instead of producing

```
forall ... do
```

as original `\FORALL`

, it produces

```
forall ... do in parallel
```

## Best Answer

You can say

The definition of

`\FORALLP`

is modeled on that of`\FORALL`

; you can't call it`\FORALL_P`

, however.
