[SOLVED] Is there a $modeswitch to enable initialized variables in {$mode tp} ?
«

January 17, 2020, 05:21:23 pm »
I want to use an initialized array variable in {$mode tp} like:
Code: Pascal
[Select]
[+]
[-]
{$mode tp}
var
a
:
array
of
integer
=
nil
;
This is not allowed (FPC 3.2.0). But for the most features of {$mode delphi} or {$mode objfpc} there is a {$modeswitch xyz} directive to enable it. In
https://www.freepascal.org/docs-html/prog/progsu105.html
I didn't find it. Does it not exist?
Thanks in advance.

Sensorship about opinions does not belong here.

mode tp doesn't know about dynamic arrays. Use either mode delphi or mode objfpc (syntax differs)

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

But this compiles (FPC 3.0.4):
Code: Pascal
[Select]
[+]
[-]
{$mode tp}
var
a
:
array
of
integer
;
i
:
integer
;
begin
SetLength
(
a
,
10
)
;
for
i
:
=
0
to
High
(
a
)
-
1
do
a
[
i
]
:
=
i
;
end
.

No, there is no modeswitch for this functionality.

This is sad news (but that's not your fault ;-). Thanks for your help, Jonas.
