The whole code is:
Code:
#!/bin/csh
if (${#argv} < 1) then
    USAGE:
    echo "USAGE: cluster_on_lev3.csh -dir <full_path Lev3 gfeat cope directory> [options]"
    echo "USAGE: cluster_on_lev3.csh -dir <full_path Lev3 gfeat cope directory> -t <value> -p <value> -c <value> -l <value> -h <value>"
exit -1 
endif
while ( $#argv != 0)
	set flag = $argv[1]; shift;
	switch ($flag)
	case "-dir":
	    set lev3cope = $argv[1]; shift;
	    breaksw
	case "-t":
	    set thresh = $argv[1]; shift;
	    breaksw
	case "-p":
            set pvalue = $argv[1]; shift;
	    breaksw
	case "-c":
            set conn_voxels = $argv[1]; shift;
	    breaksw
	case "-l":
            set zmin = $argv[1]; shift;
	    breaksw
	case "-h":
            set zmax = $argv[1]; shift;
	    breaksw
	endsw
end

I just want to put a check to make sure the sure is passing input argument with the space i.e -t 2.3 instead of -t2.3

shift

shift(1)                                                           User Commands                                                          shift(1)

NAME

       shift - shell built-in function to traverse either a shell's argument list or a list of field-separated words

SYNOPSIS

   sh
       shift [n]

   csh
       shift [variable]

   ksh
       * shift [n]

DESCRIPTION

   sh
       The positional parameters from $n+1 ... are renamed $1 ... . If n is not given, it is assumed to be 1.

   csh
       The  components of argv, or variable, if supplied, are shifted to the left, discarding the first component. It is an error for the variable
       not to be set or to have a null value.

   ksh
       The positional parameters from $n+1 $n+1 ... are renamed $1 ..., default n is 1. The parameter n can  be  any  arithmetic  expression  that
       evaluates to a non-negative number less than or equal to $#.

       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,  following 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 word splitting and file name generation  are  not
           performed.
