Of course I've understood your question, just trying to point out that
it's no longer a concern since keeping VFP is no longer a risk and
rewrite brings no additional value.
As far as I know, all clone languages (Lianja, x#, xBase++) require
changing the VFP code; as soon as you change a single line of your app
in a non back compat manner, it becomes a migration where you can't
safely step back; and here come the risks and costs.

Thierry,
All I know is that there have been a number of comments about various options
that are similar to VFP that have come out (X# is one) where VFP code will more
or less run, especially with some of the built in conversion tools.
So the question isn't whether to stay with VFP, but if there are any
alternatives that will run the VFP code without significant re-writes.
Thanks,
Fletcher

Subject: Re: [NF] Looking for current summary of VFP clones
Hi Fletscher,
Does your client really knows that, since 10 is the last version of Windows,
VFP will work as long as Windows 10 will work, and re-write and/or migration
will bring nothing but cost and risk without a single benefit (except for those
who rewrite): learning, moving data to SQL if not already, rewriting, testing,
retraining users, managing the transition with part of the app in VFP and part
in the new system (no new app ever work overnight), etc., maybe loss of
functionalities, and risk that the transition works out badly…
Seeking alternatives to FoxPro was valid until Microsoft announced that Windows
10 was the last version (in may 2015, almost 4 years ago), today it's just
seeking cost and risk for no other benefit than 'doing someting new'.
VFP is incredibly reliable; some FoxInCloud clients have FoxInCloud web apps
with over 50 forms (could be more), 50 concurrent users (could be more),
PostgreSQL database, 8 logical servers in parallel (stateless, many-to-many
relation between users and servers), running full weeks without a single error
(100% availability) while reading and writing thousands of files, tables,
memos, indexes and so forth. The busiest server runs 25k user requests per day,
that we can estimate over 1.2 billion VFP instructions, without a single error…
Bringing additional value to the existing VFP app is probably more worthy and
interesting than rewriting; eg. with FoxInCloud.
(I know I don't really answer your original question, just trying to open new
pathes).

Hi all,
I was asked for a list of current options for someone who has a VFP
application and wants to migrate it to a supported language, with the least
amount of re-work.
I have seen many options listed, but am sure how compatible the various
alternatives are. X# looks promising, but so do some of the others. And
some that I thought were good options now appear to be dormant or
discontinued. So I thought I would check with you fine folks to see if you
know where I might find a list of current alternatives and their level of
compatibility.
Thanks,
Fletcher
