> Hershel, the construct "there is a" is already in the language. It's
used to check for existence of something (object in a stack, file,
directory). Xavier just suggested new options: to check whether a
volume (it should be volume or partition not drive) is mounted
(volume in question could be local, remote, or virtual) or whether a
control is inside a specific group. The current syntax allows
checking only whether a control exists.
Yes, thanks for making me aware of it, my problem, I used looping instead
(hopefully no more).
That again proves my point that the language is a bit big and should not get
bigger. Instead I'd suggest to do some changes instead of adding operators,
to be able to combine operators, "there is a" is actual 1 operator, instead
"there" a keyword "is" and "not" are already implemented should be able to
work together. That will enable to write 'if "abc" contains not "d"' instead
of writing 'if "abc" contains "d" is false', if "whatever" exist not',
using the same concept across the board. What I would work on this moment is
to be able to use the language asis (maybe a bit reduced) to be able mix and
mach the existing keywords operators and so on.
If I'll be busy learning languages all the time I might become a programmer,
well I'm in the money making business, if it doesn't go in programming I'll
sell homes if it wouldn't go with homes I'll sell big buildings. The bottom
line is to make a living and support my family.
Thanks, no offence to anybody just expressing my self.

Unless I misunderstand what you are saying, yes, you can combine 'not'
if there is a file z then
if there is not a file z then
if x is in y then
if x is not in y then
if x is among words of y then
if x is not among words of y then
etc
'contains' seems to be the only exception to that syntax but you can say
if z contains x then
if not (z contains x) then
Also, 'contains' is the same as 'is in' just acting in opposite
direction, so you can also say
if x is not in z then
What Xavier suggested for 'there' was not adding a new operator but
extending the existing operator to new objects. That is quite
different, although I came to realize in the meantime that 'there is
a volume x' can be achieved already with 'x is among the lines of
volumes()' and checking about control inside a group can be achieved
by inspecting the owner of that control, so the new syntax would be
just a shortcut in both instances. Nevertheless it would often make
the code clearer, so I still think these could be worthwhile
additions.
