# path - CMD executable path command for ProDOS
Build with [ca65](https://cc65.github.io/doc/ca65.html)
Installation:
* Copy target to ProDOS disk
* From BASIC.SYSTEM prompt, run: `-PATH` from STARTUP (or by hand)
Usage:
```
PATH - view current search path
PATH prefix - set search path
```
Once set, binary files of type `CMD` in the specified directory can be invoked by name. The command line will be present at $200 (GETLN input buffer).
Example:
```
] -/hd/path - install it
] PATH /hd/cmds - set PATH
] PATH - verify path
/hd/cmds
] BELL - will invoke /hd/cmds/BELL if present
```
Notes:
* Allocates a 1 page buffer to store the code
* Can be invoked as lower case (e.g. `path ...`)
