So you can still write code like you do in VFP.
For example "SKIP 1" is translated to DbSkip(1) and "SKIP 1 IN
Customer" is translated to ("Customer")->DbSkip(1).
Interesting - very similar to Clipper. Clipper also allowed you to
DECLARE your own commands and a pre-compiler that translated them into
Clipper source code.
Yes remember X# is developed by Robert vd Hulst who was a Clipper
developer, and was the Visual Objects compiler developer since I believe
V2.6-V2.8. He was subsequently also developer of Vulcan.NET and the
pre-processor of X# is behaving exactly the same as the Clipper/VO
pre-processor.
fwiw I would quibble that ("Customer")->DbSkip(1) is not a traditional
function format (more OO) - I think Clipper would have had
DbSkip("Customer", 1). As I
No that is the "Aliased" way in Clipper/VO/X#. DbSkip() acts on the
current workarea, ("AliasName") will SELECT AliasName; DbSkip(); SELECT
PreviousWorkArea
*may* have mentioned before, Clipper also handled arrays /properly/ <g>.
Hehe, I would not quibble with that one... <VBG> LOCAL aArray =
{{"This", "is", "a"}, {"proper", "array", "of", {"multi", "dimensions"}}}
For free it certainly can't hurt to look!
Indeed, although a FOX membership can help in speeding up the VFP syntax
support.
