Re: Logical assignment error

["David Bradley" <bradley@xxxxxxxxxxxx>]

Gopu,
   This error simply means that you have assigned the same logical unit 
number to more than one external file. Most often, logical unit numbers are 
assigned as parameters - you can check through each Type that contains an 
external file reference and make sure that all logical unit parameters are 
unique. You should also make sure that all your logical unit numbers are 
above 10. The numbers below 10 are reserved in TRNSYS for things like the 
list file, the keyboard, etc.
Cheers,
   David
