during the summer cbip has distributed "cpath", a very handsome tool
allowing you to create human directory structures, when it was possible
to break through the famous 127-byte limit in the MS path-command.

Unfortunally I've got some troubles:

1. MS Windows 3.0 hangs in setup when scanning for win-applications
   (or just says "UNRECOV. APPL. ERR" when running setup via icon),
   reported earlier by me 

2. The new one:
   MS-DOS "backup" can give you any strange behaviour you want:
   - if your system or memory manager (as qemm-386) detects some 
     runtime/address errors you can get 386-exception *13* when trying 
     to execute some ascii strings or nulls...
   - you can get some runtime error (BIOS? QEMM?) as wrong date, null-pointer,
     zero-divide, ....
   - or *backup* may complain about wrong/missing source
   - or just simply hang

Has anyone discovered other commands where Microsoft introduced their 
defensive >;-) programming ideas (when they are copying zero-terminated 
strings without checking if their length is okey to put in the receiving 
buffer - I assume that it is one of the first thing one to has to learn
when programming computers????), please let me (and others) know,
I cannot live without *cpath* and *long paths* and *human directory 
structures*, so I prefere to know which commands require shorter path so 
I can make some tricks around them...
