-
- Leonard,
-
- I have a dBase IV database that was created on a PC and now I
- am trying to run it in FoxBASE on the Mac. Apple File Exchange
- converted the .dbf, .prg and .ndx files just fine but when I
- tried to run it under FoxBASE I am running into problems.
-
- I think everything I need is there but there are probably some
- extra commands that need to be added into the FoxBASE .prg
- files to make it work.

-
- personally, i like Foxbase. i have programmed in dbase, and that is part
- of what attracted me to it.
-
- your dbf files are directly transferrable, and many of your prg files
- should also be ok. report forms, screens, etc. don't translate as
- well....
-
- hope this helps

- Using apple file exchange is enough. you will have to regenerate
- any indexes you are using, though. Frankly, it is really painless
- at least as far as the databases are concerned.

- Actually, FoxBase (or now Microsoft, who bought them out after
- they figured out there was no way in hell they could ever get
- a good database porduct developed) says that when foxpro for
- the mac comes out (4th quarter release expected), all of
- the screens, reports, etc. should be directly transferrable.
-
- If you are serious about developing these databases on the Mac
- (there are many skeptics out there), these products deserve
- at least the once over.
-
-
- Hope all of this is helpful.
- cheers

-
- Reading a .dbf file into ANY Macintosh database or calculation application
- is no problem. I can t figure out an application program that does not
- understand .dbf
-
- Although I am no user of 4D I realize that 4D is the most widely known and
- used implementation of a relational database on a Mac. This is for it s
- power and Mac-friendliness.
-
- The question is whether you would like to work in a mixed environment. In
- this case you have to be cautious. I for one do not know of any DOS
- connection with 4D.
-
- By the way I recall that there is another product called OMNIS you might
- want to know more about.

- You should have a look at Blyth's Omnis before you make a decision.
- It provides a neat front end for Mac and Windows environments and can
- be linked with a SQL server if you need a 'really' relational system.

-
- Fox can do these operations, sometimes with a bit of code, because it
- has a JOIN command and can define relations on the fly to do things like
- INTERSECT etc. (I have some sample code somewhere - it's a few lines).
-
- 4D can't because it can only do programmed lookups (ie: search for this key
- ) or use pre-drawn relations - it can't do relations on the fly.
-
- >Looking through the MacWarehouse (UK) catalog 4D Pro costs 899 pounds
- >compared with 295 pounds for FoxBase. I mean, is 4D so good that it
- >has to charge so much?
- YES - if you need to develop complex user-interfaces 4D is several ties
- faster than Fox and can do some things that are difficult if not impossible
- in Fox.
-
- If you need to do sophisticated data manipulation then Fox may be more useful
- although 4D has some nice array and set manipulation. Fox is far better at
- crunching lots of data in files and, as it uses the dBase model, you can use
- temporary files with abandon - 4D contains all data in a single file and has
- major problems with space re-use and indexing overhead.
-
- If you DO get into FoxBase, be aware that the FoxPro version for the Mac is not
- likely to be out until third quarter 93 - at this point it will have compatible
- code across DOS, Mac, Windows and probably Unix. Looking at FoxPro v2 for DOS
- (now) will give you an idea of the sort of language enhancements - including
- built-in SQL.
-
- If you (or anyone else) is using FoxBase+/mac right now I have a comprehensive
- list of hints I'm happy to mail, as well as a couple of shareware externals
- I've written that significantly improve the user interface for scrolling lists
- and allow a double-clickable BROWSE.
- >I've developed applications with dBaseIV on the PC and what I want to

- FoxBase+/Mac is VERY compatible with dBase III+ (catalogue and a couple of othe
- r
- commands don't work) to the extent of handling DOS-style volume and directory
- paths!
