string-match error

string-match error

Hello y'all,

I am having problems using string-match. I have created a small script
that calls string-match and I get:

/home/ariel/console/mce/tests/./panda.scm:4:9: In procedure module-lookup:
Unbound variable: string-match

If I start guile and then use string-match there is no problem:
scheme@(guile-user)> (string-match "a" "a")
$1 = #("a" (0 . 1))

It also works if I start guile and then load the file:
[ariel@oc6281107537 tests]$ guile

Enter `,help' for help.
scheme@(guile-user)> (load "panda.scm")
#(a (0 . 1))

The file contains:
#!/usr/local/bin/guile \
-e main -s
!#
(display (string-match "a" "a"))

Is there something that I am missing?

thanks,
ariel

As it says in the "Regular Expressions" section of the manual:

  "Before using the described functions, you should load this
   module by executing `(use-modules (ice-9 regex))'."

> If I start guile and then use string-match there is no problem:

It seems that the REPL starts with (ice-9 regex) loaded by default.
