Minor fix to better deal with commas.

Thanks, yes that is simpler.
Code: Pascal
[Select]
[+]
[-]
const
cLegals
:
set
of
char
=
[
'+'
,
'-'
,
'.'
,
','
,
'0'
..
'9'
]
;
function
IsLegal
(
c
:
string
)
:
boolean
;
begin
result
:
=
(
Length
(
c
)
=
1
)
and
(
c
[
1
]
in
cLegals
)
;
end
;
I tried something similar and it did not compile.

It is useful, but can use some clear optimizations. (just speed, and factoring out the lcl dependencies)

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

Very nice, thanks! It may have some useful functions for me. It looks like the Vincenty code is from the same source as mine, identical variable names, etc.

Hi.
Look at here. True text in Russian. If you need a program (module, unit) for translating the symbolic representation of angular values into radians (or vice versa) I can provide it to you. (I'm a surveyor by profession).
Sorry, but with English I feel bad
