Foreach loop through subdirectories in csh
Hi

You might find it very trivial but actually don't know how to loop through all sub-directories and their child directories into a csh. bash was easier I believe but here I am, stuck with csh. So elaborately here's my problem:
Let's say I have my parent directory named C-H/ under which I have C2H3O1/, C2H4O1/...let's say under C2H3O1/ I have several subdirectories like CH2CH2OH/, CH3CH2O/, CH3CHOH/. Inside each sub-directories I have several child directories likeVAS-S0001-001-Ru_001/,VAS-S0001-002-Ru_001/,VAS-S0001-003-Ru_001/. Inside all of them reside OPT-0/, OPT-1/ inside which my job input files and job scripts reside. I wrote a script that I'd like to run inside each child directory that modifies some input files and submits the job. I would like to run my script one time under C-H that'll go through each directory and submit my job.

Here's the silly thing that I have:
Code:
#!/bin/csh
set dir=`*/*/*/*/`
foreach $dir
 /scratch/scratchdirs/sol/Scripts/QMcalc/GEN_POSCAR
end

I know I'm doing something very very wrong, I don't have a counter for the foreach but how do I set that since the number of directories might be different for different cases? Thanks a lot!

break

break(1)                                                           User Commands                                                          break(1)

NAME

       break, continue - shell built-in functions to escape from or advance within a controlling while, for, foreach, or until  loop

SYNOPSIS

   sh
       break [n]

       continue [n]

   csh
       break

       continue

   ksh
       *break [n]

       *continue [n]

DESCRIPTION

   sh
       The break utility exits from the enclosing for or while loop, if any. If n is specified, break n levels.

       The continue utility resumes the next iteration of the enclosing for or while loop. If n is specified, resume at the n-th enclosing loop.

   csh
       The  break  utility  resumes  execution after the end of the nearest enclosing foreach or while loop. The remaining commands on the current
       line are executed. This allows multilevel breaks to be written as a list of break commands, all on one line.

       The continue utility continues execution of the next iteration of the nearest enclosing while or foreach loop.

   ksh
       The break utility exits from the enclosed for, while, until, or select loop, if any. If n is specified,  then  break  n  levels.  If  n  is
       greater than the number of enclosing loops, the outermost enclosing loop shall be exited.

       The  continue utility resumes the next iteration of the enclosed for, while, until, or select loop. If n is specified then resume at the n-
       th enclosed loop. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words that follow a command preceded by ** that are in the format of a variable assignment are expanded with the same rules as a  vari-
           able  assignment.  This means that tilde substitution is performed after the = sign, and also that word splitting and file name genera-
           tion are not performed.
