[SAC-HELP] Fwd: Error messages from getfhv etc

[Neil Selby]

Brian,

thanks - yes you are right, the current version of the library gives a Warning rather than an error.

I wasn't aware of the sac_warning_off routine, and it looks like it does exactly what I want.

Is there a function which returns the error/warning message associated with a given code?

many thanks,

Neil
