Comp as LargeInt
«
on:
August 06, 2021, 11:59:19 am »
When using below code in MS Windows it compiles fine and runs the software. But when compiling in Linux (Mint 20.2) it fails to compile with:
"Incompatible type for arg no. 1: Got "Comp", expected "Int64"
From what I have understood the type "Comp" is defined as an Int64 (according to the reference for the unit 'System')
Anyone that has a hunch about what I have misunderstood?
Code: Pascal
[Select]
[+]
[-]
var
TimeStamp
:
Comp
;
begin
TimeStamp
:
=
TimeStampToMSecs
(
DateTimeToTimeStamp
(
now
)
)
;
.
.
.
XXXX
.
FieldByName
(
'created_at'
)
.
AsLargeInt
:
=
TimeStamp
;
.
.

On some targets using x87 FPU, comp is the x87 FPU comp type.
Win64 uses SSE for fpu afaik per Microsoft decree, and *nix uses x87.
In general, it is best to simply never use comp. It is a legacy type that is best forgotten.

Addition to Marco:

It is also not portable.

Specialize a type, not a var.
