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...
