system variable list

[dominik(at)astro.uva.nl]

Hi,

is there a way to get a list of IDL system variables into a string
array?  I can do it with

  help,output=lines,/system_variables,/brief
  system_vars= strsplit(strjoin(lines," ",/single)," +",/regex,/extract)

but that is considered to be unsafe because of the use of the output
keyword with help.

Are there any other ways to do this better?

Thanks

- Carsten
