现有一c-shell file, 它可以调用一个fortune程序, 但是每次只能执行一个输入纪录,得
到一个输出结果. 为了能让它执行多个纪录, 另外写一个脚本程序(use perl),做循环,每
遇到一个纪录九调用一次c-shell file, 处理这个纪录, 得到输出结果, 请问在perl中如
何调用c-shell file?
thanks in advanced

I think your problem can be solved by using c-shell alone.
Just read some tutorials on c-shell.

thanks, it will be good if i can do so
but my many records(150,000) are all in one file, i need to recognize one
record,pick it up into one single file, as what you said, just use c-shell
to run the fortune program, get the result for this record, print it into
the result file,
then recognize the next one....i think i need sth like pointer to move in
my big file, to recognize each record one by one, do you think if it can
be done so?
Thanks again

Just give you some hints, you need to get c-shell tutorial
and impliment yourself.
Say your fortran is run.exe, data is h001.dat, you run it as
run.exe < h001.dat>run.h001.dat.out
Now you have 100 data files, as h002.dat, etc. You can
[[
for datafilename in "ls *.dat"
do
run.exe < datafilename> run.datafilename.out
done
]]
Note the above is illustration only. You need to read the c-shell
turorial to get things right, which should not be that hard.

you are right, but right now my situation is actually my 100 data files
are all in 1 big file, not individually 100 seperated files, I wonder
how c shell recognize each record in this big file? and then pick it up
into the standard input file one by one?
am i making myself clear? thanks :-)
btw, there are 150,000 records in this big file, maybe more in the
future

It is easy to split big file into small pieces, as long as you
know the seperator or how many lines of each. You can even do
that in Fortran within 5 minutes.

wait a minute, can't you just modify the dam FORTRAN and
solve the problem once for all?

haha, this is my another problem that i think i can't solve
actually, this fortune program is Amsol
http://comp.chem.umn.edu/amsol/
i dont' think i can modify that program, wuwuwu
also, i also need to modify again when new version is released

Then try to split the file, You can do it in Fortran, C, C++, c-sh,
tcsh, bash, perl. python, ...
Too many choices.

you mean trying to split this file into 150,000 individual files?
is it a little bit crazy?
if i can use other program that makes a loop to run this c-sh file,
do you think if it is more easier than to split it??

Splitting is easiest for you.
