[Gambas-user] Help with some parsing

[Emil Tchekov]

Hello Doriano,

I have to excuse me - it was never my intention to insult your, as it seems
deeper going feelings, regarding this particular 2 Bytes :-D

Ofcourse you are right - they are (and will be in the future also) still in
use...

But here is the point where I do not agree with you:

I do not know how old are you... My first "date" with CR&LF was on my very
expensive (>4000 USD) Apple ][ with the huge ammount of 48 KB RAM, 16 KB
ROM, 144 KB Floppy Disk and rare extension - Video Card allowing me to work
with 80x25 chars instead of the usual 40x25 ... Not to mention the
extraordinary calculation power based on the 1 MHz 6502 CPU ;-).

So please excuse when I am calling this "stone age", but my very simple
mobile phone laying in my pocket offers 2 GB of storing capacity on volume
that the old Apple used to store about 16KB and about 300 MHz RISC based
power...

It was not a try to reduce the meaning and importance of those command
chars - but simply to show how long they are in use...

Very best regards

And one more time excuse my lack of respect

Pardon me to point out. I disagree,
chr$(13) is CR; chr$(10) is LF.
While it is true they are an old standard, saying they are "from the
stone age" is not fair. HTTP protocol relies on CR-LF, and you must
admit that HTTP protocol is well alive - not a "stone age" standard. The
fact CR-LF is so old is a proof of its power.
Moreover, text files are the most expressive and versatile form of
digital data. Html, Xml, Svg, Postscript, PDF, are all in wide use and
are based on ASCII, and so they contain CR-LF sequences.

The fact Unix/Linux uses a single LF instead of a CR-LF is pretty
marginal - it was simply a design choice. A windows HTTP server can take
text files from disk and serve them verbatim, while a Unix HTTP server
has to translate them (to add the missing CR). Anyway, the concept is
the same. Most programs today can cope perfectly well with this two
standars.

In the end, the only thing I wanted to say is that CR and LF are far
more than what you depicted, and they are still needed.

Regards,
