[slang-users] goto statement in slang

[Tolga Guver]

Hi,

I am a newcomer to slang, I have number of scripts written in IDL and 
want to convert them into s-lang scripts to be able to use within the 
ISIS (Interactive Spectral Interpretation System) software.

I was wondering if there is anything like a goto statement in IDL.
I saw in the mailing archive 
(http://mailman.jedsoft.org/pipermail/slang-users-l/2007.txt) that 
someone used something like

SLang_verror (SL_MALLOC_ERROR, "Cannot Create ARRAY for Attributes!! " ) ;
            goto attribute_error ;
          }

      if (-1 == SLang_push_array (at, 1))
          {
        SLang_verror (SL_INTRIN_ERROR, "Cannot Push  Attribute Array on 
Stack !! " ) ;
            goto attribute_error ;
          }


    return;

attribute_error:

but when i tried a similar expression i get an error telling goto is 
undefined.


best,
tolga
