Hallo,
I get allways (10 times at least) the same result:
-------------------------------------------------------------
\starttext
\startluacode
math.randomseed(os.time())
\stopluacode
Encode your Name and Surname as a
\startluacode
local a = {'null-terminated', 'dollar-terminated', 'Pascal'}
context('%s string', a[math.random(1,3)])
\stopluacode
\stoptext
-------------------------------------------------------------
How can I randomize this?
Wolfgang

ConTeXt saves the random value in the tuc file to get the same output in
each run.
Delete the tuc file with 'context --purgeall'.

Hmm... which version are you using? I do get a ranom output each time.
Tested with 2009.12.31 and 2010.03.20.
Since the math seed is set after \starttext, it should overwrite the value
after reading the tuc file.
Actually, I consider saving the random number in tuc file to be a
misfeature. A random sequence generator should generate a random sequence.
If I want the same behavior all the time, I can use
\setupsystem[random=12345] (which should also set
math.randomseed).

Hello,
is there please any equivalent for LaTeX psfrag package (it can replace
the text in eps images)?
greetings
Jan Pohanka

the reason is that otherwise (esp if the randomization produced
different input, graphic sizes, etc) you can get oscilation and endless
runs due to never quite right multipass data which is pretty hard to debug

Same here:
# for j in `seq 1 100`; do context test.tex &> /dev/null; pdftotext
test.pdf -|grep Encode; done >> out
# nl out |tail -1
100 Encode your Name and Surname as a null-terminated string
# grep 'Encode your Name and Surname as a Pascal string' out |nl|tail -1
33 Encode your Name and Surname as a Pascal string
# grep 'Encode your Name and Surname as a dollar-terminated string'
out |nl|tail -1
35 Encode your Name and Surname as a dollar-terminated string
# grep 'Encode your Name and Surname as a null-terminated string' out
|nl|tail -1
32 Encode your Name and Surname as a null-terminated string
which is pretty good for only 100 samples
