- { LEFT TO DO: }
- {--------------------------------------------------------------------}
- { o DiskFree / Disksize don't work as expected }
- { o Implement SetDate and SetTime }
- { o Implement EnvCount,EnvStr }
- { o FindFirst should only work with correct attributes }

- {
- History:
- I have made an temporary fix for GetEnv('path')).
- Now you get a string with all directories in your
- path env. You can now do a fsearch('myfile',GetEnv('Path')).
- This fix is just a tempfix, can be removed in the next
- release. (or fixed).

-
- History (Nils Sjoholm):
- 10.02.1998 First version for Amiga.
- Just GetDate and GetTime.
-
- 11.02.1998 Added AmigaToDt and DtToAmiga
- Changed GetDate and GetTime to
- use AmigaToDt and DtToAmiga.
-
- Added DiskSize and DiskFree.
- They are using a string as arg
- have to try to fix that.
-
- 12.02.1998 Added Fsplit and FExpand.
- Cleaned up the unit and removed
- stuff that was not used yet.
-
- 13.02.1998 Added CToPas and PasToC and removed
- the uses of strings.
-
- 14.02.1998 Removed AmigaToDt and DtToAmiga
- from public area.
- Added deviceids and devicenames
- arrays so now diskfree and disksize
- is compatible with dos.
