I did not plug Seed7 as a solution for incompatible
Pascal dialects. The beginning of the mail contains
information about the 'sleep' function and the
paragraph about Pascal and ****tability can also be
helpful. The last paragraph should just show that
although I am a critic of Pascal I do not hate it.

IMHO the number of implementations does not play a role
for ****tability. C has many implementations and the
****tability problems which exist in Pascal are simply
not present. The problem is that many of the early
proponents of Pascal (and if you look at this discussion
also current proponents) simply do not care about
****tability. This has to do with the areas where C and
Pascal came from. BTW. There is some classic article
about Pascal and C from Brian W. Kernighan:
http://www.lysator.liu.se/c/bwk-on-pascal.html

You are right that there is currently only one
implementation of Seed7, but this implementation
runs on various operating systems (unix, bsd, linux
windows) on different hardware and with several C
compilers. Additionally this implementation is open
source (GPL) and therefore can be used to ****t Seed7
to even more places. I tried to reach that level of
****tability with Pascal (a predecessor of the current
Seed7 interpreter was implemented in Pascal) and
failed tatally because of the incompatible Pascal
dialects.

A compiler is not the end of the story about
****tability, but just the beginning. You need also
****table libraries for various areas. I admit that
many libraries are still missing in Seed7, but at
least something (strings, resizeable arrays, hash tables,
large bitsets, big integers, rationals, complex, time,
duration, ****table graphics, reflection) is there.
I guess that at least some of this libraries are not
available in Standard Pascal. And it makes a difference
if a feature is present in some implementation or is
granted to be always present.

The license plays also a role. The best library
does not help when it is not usable with another
compiler or operating system.
