Re: st: Re lincom not recognising macros

[Jennifer Dent <JDent@sgul.ac.uk>]

Dear Nick

Apologies for the typos.

Re using the 'indirect' solution - I want to run the function several

(local) variables will change slightly. I'll have a think about which is 
more efficient, given the solution.

Thank you for your help,

Jennifer
