access to Unix environment variables from within grads scripting language

[bernd.becker at METOFFICE.GOV.UK]

Hello!

I would like to access System environment variables
during run time of a grads script.
The following function doddle allows me to do that,
but it doesn't look nice.

How can I make the following code much slicker?
Regards,
Bernd.

function doddle ()
'!echo $base >./erp1'
record2=read(erp1)
result=sublin(record2,2)
rc=close(erp1)
say result
quit
return
