Re: [fpc-pascal] Typed Constants vs. Variables

Where/why would one use a typed constant vs. a variable. i.e.

myVar : double = 2.0*Pi;
It seems to me the typed constant is superfluous and can potentially
lead to bugs.
Typed constants predate the existence of initialized variables.
Furthermore,
a) typed constants are initialized once (when the program starts), and
if changed keep their value until explicitly changed again (even if
they are declared locally in a procedure/function, and over multiple
independent invocations of such routines)
b) conversely, initialized variables are initialized every time their
scope is activated (or whatever the proper term for that is: once in
case they are declared in a program/unit scope, and every time a
function/procedure is entered if they are declared locally in a routine)
c) typed constants can be made read-only by using the {$j-} switch

This was the bit of information which was not getting through to me before. Francisco, In FPC, there are two types of constants: ordinary and typed. Ordinary constants are what you were thinking of while typed constants act a bit differently as Jonas and lele wrote. My confusion was that typed constants and initialized variables seemed to me to behave exactly the same - that is, acted like variables - until I learned the subtle difference in (b) above. Although I can appreciate why the term typed constant was selected for such a language feature, it was confusing to me since I tend to think of constants as being constant and one has to be careful in realizing the difference lest things don't work the way as one might expect. - ROW ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Hi, i also try to get free pascal running on my freerunner. i needed many tries to get a running ppcarm for my device. (In reality i didn't know why it worked in the last run ... but it did, and so i don't ask :) ) now i let the freerunner recompile the hole fpcbuild. But that could take some time. ... you know how fast our devices are :) i hope that all things will work well after that . i used these compiler options : OPT=-dFPC_ARMEL -O- -dFPC_ABI_EABI NOGDB=1 i tell you if it works or not. it could just be hours from now :) Have you cross compiled the hole free pascal or just the ppcarm? you should be able to crosscompile the hello programm by using the crossppcarm compiler on your normal machine. (And don't forget to use -dFPC_ARMEL -O- -dFPC_ABI_EABI.)

That documentation is not really complete. The supported settings are:
* FIXED, DEFAULT, NORMAL: the default behaviour, and behaves as
described in the docs.
* 1, 2, 4: the set size depends on both the low and high value of the
set element type (e.g., a set of 16..23 will be 1 byte in case of
{$packset 1}), with
a) the lower bound rounded down to a multiple of the packset setting
expressed in bits
b) the upper bound rounded up to 'a multiple of the packset setting
(in bits)' minus 1 (e.g., 24 is a multiple of 8 bits in the above
example - -1 = 23)
c) if the set size would be 3 bytes after the above calculation, it's
changed to 4 bytes
d) if the set size would be greater than 4 bytes after the above
calculation, it's changed to 32 bytes.
* {$packset 8} is also supported, but kind of nonsensical in the
current implementation (will always be rounded up to 32 byte, since
the set size will always be 4).
