I'm trying to read the following into an ascii analogin record:

"=V913 1.13e-04;59;11;0;0"

and to extract the 1.13e-04 or whatever. Using <%5k%f> just times out and so does <=V913%f>. Using %e makes no difference. If I read the value into a stringin record, there is no problem apart from the fact that it's a string.

Any suggestions?

I don't know specifically about drvAscii format strings, but the sscanf format that would work is "%*5c%f".

If you don't find a format string that will work, you could just grab the
whole string and parse it with an sCalcout record, using the above format.
