I don't understand this, can you provide an example ?

I don't think that argument holds water. Concatenatio

Dynamic arrays are incredibly convenient for purposes like signal processng,

Are you serious ? I have been using dynamic
I encountered an odd problem, however reliably reproducible under both
windows 7 and 10, 32bit, with FPC 3.0.2 and 3.0.4. (NOT with Lazarus 1.6.4
which uses FPC 3.0.2 but 64bit)
When compiling my program with debug info using fpc -B -g, the compiler
hangs just before generating the exe file. It se
As I understand this: It may sometimes well be necessary to write your own
destructor to clean up. But if you do this, don't call it foo; call it
destructor and override it: destructor destroy; override;
In your own destructor method, don't forget to call inherited in the end.

Just a note - I learned that for very short "for" loops it may be even a bit
faster to count downwards (to zero) rather than upwards if possible, because
the comparison to zero is very effiicient. Not sure though whether that
still makes a difference on modern processors.

Steve probably means "when passed 'E1' or 'E2' etc."
Indeed IsNum ('E1') interprets it as zero and delivers TRUE.

I would do it like this
test(TBytes.Create (65, 66, 67));
