Re: [TRNSYS-users] External data file for type43a & type20

[David Bradley <bradley@tess-inc.com>]

Paul,
 Type43 accesses a data file that uses the standard TRNSYS format
for external data (Type20 uses a different format, I believe). The format
of the data file is described in the 08-Programmer's Guide (section
8.4.4.4.) If you can't figure it out from the syntax description, please
send me your *.tpf, the data file, and whatever other files I might need
in order to run the simulation.
Cheers,
 David
