Hi Alan,
Well done and thanks for the testing work you doing.
Hmm not sure about VFP recognizable, it looks quite X# to me... :-P
Will just bash your code a little bit:

use "customers.dbf" new shared index "customers"
select customers

if rlock()
replace creditlim with 1000
unlock
endif
<bashmode:ON>
You need the RLock() (record lock) function due to shared mode. You can
have multiple users trying to update the same record concurrently. If
you opened the DBF in EXCLUSIVE mode, it would not be required.
<bashmode:OFF>
Once you understand the functional/class handling way of DBF
interfacing, you can shorten this code too. Look in the help file for
DbServer etc. There are very few X# users that still do command based
coding.
Another tip. If you set the commandline switch /ppo to be included in
the compilation, you will see in the .prg folder a .ppo file created.
If you open this you will see what the pre-processor did to your code to
make the compiler understand your VFP XBase commands.

PS: By the way, are you using Visual Studio or XIDE for this work?
