octave2.9 in scripts and curly braces

[Eric Chassande-Mottin]

hi,

I'm having a problem with octave 2.9.9 used in a
script like the one below:

-----------------------------------------------------------------------
#!/usr/bin/octave2.9 -qf

argument=argv{1};
-----------------------------------------------------------------------

the script gives the following error:

error: built-in function cannot be indexed with {
error: evaluating assignment expression near line 3, column 9
error: near line 3 of file `./test.sh'

curly braces are both used to index the arguments of the script
and structures in Octave v2.9, hence the error.

is there a simple escape?

thanks,
eric.
