[fpc-pascal] Re: ++ and -- ( and +=, -=, ...)

[Gerhard Scholz]

Semantically, it's not the same, but

a += b

can be replaced by

inc ( a, b ) ;

It's readable, it looks like normal standard Pascal; and it's clear that the 
address of a is
calculated only once.

If a,b are not ordinals, inc could be overloaded.

Greetings

Gerhard
