AS400 conversion

[Tom Anderson]

          I posted a few days ago about migrating all my code and db structure to a Windows platform.

 

          While it will be a daunting task, it looks like at this point that Providex is the best option out there.

 

          Some questions:

 

1.    Providex holds an annual conference (in September). Is this worth attending for a pvx newbie?

2.    Are there any contract programmers out there that might be interested in giving a hand with this?

3.    Any suggestions on the best way to get up to speed with pvx?

4.    Any gotcha’s?

 

Thanks for any assistance!

1 - yes, even for a newbie it's worth going to the PVX plus conference. There's lots to learn. 

2 - if you go to the conference I'm sure you can network a bit and get in touch with some contractors out there. There are a few contract programers out there and the best way to get in touch is the PVX mailing list and the conference. 

3 - what I usually do is read the latest info on the website, download the manuals and browse through them and communicate on the PVX mailing list. 

4 - can't think of any botches. You should ask people on the PVX list that have done the Bbx -> PVX migration

Hope this helps.

Hi,

First # 4, the gotcha is ya don't have it...

If you have not done so already, subscribe to the mail list and see the wealth of information.

providex-...@pvxplus.com

Once you get there, pose the question there about moving from AS400.

There are archives that you can see ALL of the posts for a number of years.

Conferences are about every 18 months, so if you plan on getting info, go to this Septembers version.

Like Christian said, RTM, it is good for you.

I have done a number of BBX to PVX conversions and there are many more people out there (maybe in the next hood) that can help. There are tools in PVX that do most of the work.

Once you get here, enjoy.

Walter

Tom,

 

#1 – Yes they are worth attending. Both for the product, and the chance to talk with others using the language.

 

#2 – There are many contract programmers out there that could help. My company is one of them.

 

 

As to gotcha’s, from what I remember of conversions with others who’ve had an AS400 based business basic, the conversion will not be an easy one. Early business basic fragmented into several derivatives, where each derivative had differing behavior. The derivatives that were ported to AS400, are different from the ProvideX/PVX Plus/BBx/Thoroughbred styles, and there are no conversion routines out there that I am aware of for one derivative to another. That’s not to say it cannot be done, but there likely no conversion packages that will apply 100% to what you want. The conversion will have to be customized and likely heavily customized.

1. there is a DireXions convention in setp. -
IMHO deffinately worth while going. - check out www.pvxplus.com

2. I have successfully migrated BB (mostly tbred) to providex. - this
includes Report-4 reports and IDOL-IV screens, as well as the more
advanced #FORMAT (equivs for FORMAT INCLUDE, FMT, ATR, etc)

** note to the good folks at tbred ** - the migrations I did were
for customers that were phasing out Tbred ANYWAY in favor of PHP, JAVA
.net, c#, etc. *** - they did this as a result of lack-luster sales of
a character based product - and 'web only' interface was not the look
and feel they were seeking - I simply came in and offered a faster
alternative.

Personally, I still feel some apps are far faster & even more friendly
in chui. - there are many benefits to Tbred - like Data-Safeguard
always encourage folks to stay with Tbred when GUI is not a paramount
imperative! (chui development is faster & more stable as well)

3. Gui is step-by-step - 1st step is to simply make sure apps are
running "as is" in pvx. - GUI can be added, at first to existing
character screens - GUI & Chui in provdiex are "layers" so they
co exist nicely on the exact same screen. ex: buttons, graphic queries,
mouse control (someone clicks on a Chui Text field) - etc.

eventually, of course, each panel can be designed in nomads,
more-often-then-not existing code can at least be 'partially' stolen
into the new all-gui panels.

4. I have eliminated just about every 'gotcha' so far - the biggies
were writing a set of programs to create normal stand-alone programs from
report-iv and Idol screen definitions (that essentailly do all or most of
the original Idol)

Mike King at providex was instrumental in re-compiling the basic for me
-- often within 48 hours from request -- to support some features from
Tbred into pvx to facilitate conversion.

(not too many companies where the owner is also the chief developer
and 'average joe' can actually talk to him and make requests, much less
have the request granted within a 48 hour period).

hope this helps
feel free to email me directly if you'd like

[Sam G]

there is a paper in the pvpxplus that deals specifically with a GUI
migration path.

it does begin, as I stated eralier, with first porting 'as is'.

worth while reading - be sure to call the folks at pvxplus (like David Twiddy)
am sure he can help finding that papers

Gord,

i think there was a BB product called PLUTO to run relgular BB
apps (esp tbred) - if so it should be pretty str8 fwd ?!

(from what I remember)

[Tom Anderson]

The 400 bb came from the PLUTO product produced by Southwest Data Systems in LA.

The Pluto bb was very straightforward. My code came from Pluto to the 400 product called X/TEND.

Tom

Gord,

(from what I remember)

I suspected that (see previous post)

Pluto s/b pretty str8 forward to port back to basic
some utility will have to be written on the AS-400 to create an ascii
'file-ball' (as opposed to tar-ball) that conaints, in ascii form
the files and listed programs. "should" be no big deal.

(hopefully AS-400 is not EBCDIC - but not end of world since it can be
translatated)

also, hopefully, AS-400 has something like FTP.

hope this helps

Sam

[Tom Anderson]

Sam,

Already have the ability to get programs in listed ASCII format in a straight text file. Got that utility years ago. So that part is done.

So, does pvx have a utility already written that can take the ASCII file and put back into BB?

Thanks!

Tom

hope this helps

pvx utilities have a program called
*pg.cnv (callalbe)

That converts ascii programs to pvx

You almost don't need this ...

Here is a line of code from *pg.cnv that does this (in the middle of a CALL,
mind you) (I edited this line)

00550 P$=PGN; LOAD i$; SAVE O$; LOAD P$; GOTO 00560

I$ can be an ascii file that is a program - O$ will be the convertd program

Sam

[Sam G]

follow up

you'll still need a 'bundle' and 'un-bundle' type program to "collect" all
programs and data into a single file (or programs in one file & all data in
separate file) on the as/400 and pvx box respectively.
