The script_explode_str procedure (magic scripting) allows to easily get all arguments passed to a spell.

Code

magic-base.sex
 (PROCEDURE script_explode_str (delimiter str varname maxparams)
   (FOR a 0 maxparams
       (BLOCK
           (IF (< (strlen str) 1) (BREAK))
           (SET arglen (strlen str))
           (SET argoffset
               (if_then_else
                   (contains_string str delimiter)
                   (strstr str delimiter)
                   arglen))
           (SET arg
               (if_then_else (== arglen argoffset)
                   str
                   (substr str 0 argoffset)))
           (set_script_str caster (+ (+ "@" varname) (+ a "$")) arg)
           (SET str
               (if_then_else
                   (> arglen (- argoffset 1))
                   (substr str (+ argoffset 1) arglen)
                   "")))))

Example Usage

(CALL script_explode_str " " target "foo" 2)

In the above example, the target string is split at every " " (space) and each argument is named fooX in which X is an integer ranging from 0 to 2.

If the target string is, let's say, "hello world !" this script will make 3 arguments: @foo0$ (hello), @foo1$ (world), @foo2$ (!). These variables are then available for use in scripts or in the magic system itself (with get_script_variable)
