[SOLVED] Changing file names

I have written a csh script that changes the name of file from src to dst.

I am getting the error below:

Code:
TESTAmvfiles
DONE TESTAmvfiles
set: Variable name must begin with a letter.

The csh script is:

Code:
#!/bin/csh

#       o   Sets permissions for other users (that are not in group),

#       a   Sets permissions for all (owner, group and others),
#           e.g.: "a-w" disables write access to the file for everyone

#
#    Matching patterns:
#
#    Instead of: set match = `echo $f | grep $fsrc`
#    one can use: set match = `echo $f | awk -v src=$fsrc '$0 ~ src'`
#
#    find path -name "*.fext" -exec rm -f '{}' ';'
#    find path [expression]
#
#    -exec command
#    Execute command; true if 0 status is returned. All  following
#      arguments to find are taken to be arguments to the command until
#      an argument consisting of ";" is encountered.  The  string  "{}"
#      is  replaced by the current file name being processed everywhere
#      it occurs in the arguments to the command, not just in arguments
#      where  it  is alone, as in some versions of find.  Both of these
#      constructions might need to be escaped (with a "\") or quoted to
#      protect them from expansion by the shell.  See the EXAMPLES sec-
#      tion for examples of the use of the "-exec" option.  The    speci-
#      fied  command is run once for each matched file.    The command is
#      executed in the  starting  directory.    There  are  unavoidable
#      security    problems  surrounding  use  of    the  -exec option; you
#      should use the -execdir option instead.
