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

[David Bradley]

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
