Stephan,
I am not aware of any such components. If you are planning to put
your component into an external DLL (ie not into the TRNDll.dll)
then you will need to look at using something like the following:
Integer lu,returnVal
lu = PAR(1) !read the parameter that is the file's logical unit number.
filename = getLUFilename(lu) !use an access function to figure out what the associated file name is
returnVal = closeFileIVF(lu) !use an access function that forces the TRNSYS kernel to close the file. NOTE: returnVal is meaningless; it is just the result of the function call.
Open (unit=NNN,file=filename,status='UNKNOWN',err=402) !now reopen it using your own logical unit number (denoted NNN). You can reuse lu if you want.
Rewind(NNN) !make sure you are at the beginning of the file.
Read(NNN,...) !now use standard FORTRAN Read, and If statements to find what you are looking for in the file
Backspace(NNN) !back up one line once you found what you were looking for.
Write(NNN,...) ! once you have found what you are looking for and backed up one line, use a Write statement to replace it
Close(NNN)
Best,
David

Hi everyone,
I am writing to ask if someone did make a
type in TRNSYS that enable us to open a user defined text
file, search for a user define value and replace it with
another value.
Many Thanks!!
Louis,
