RE: [EnergyPlus_Support] Re: Maximum File Path Name for Macros

Hi, Linda

I could not fine the helpdesk site where the new EPmacro is located.

I do not have problem myself, because I do not use long path and file names. (One form of energy saving)
====================
The Window directory length limit is still 255 per item. However, in the imf text file, the text editor may add a <CR> at near 80 char length position, when the "wrap" is turned on and saved under certain 'text' condition. When that happens, the path name may behave as truncated. I test this condition by changing the display width and see that the path will flow back to the previous line.

128 char length is a safer limit to use. Path and file name total must be < 255 in the 16 bit windows or DOS sindow.

1) Did you download the new ep-macro version from the helpdesk?

2) There is likely a limit -- I will try to change that for the next release (up to a point -- I believe the path/file name limit is still 255 characters for Windows)

Sorry. Bad communication on my part...due to rushing as usual. The include statement (which works) is just supposed to illustrate how I'm including as one can use a prefix for the file path string up to the file name as well. The last file where i noticed this is now called J:\Projekte\BEWERBUNGEN\BBI Simulation\Eplus\Simulation Runs\Actuell\Dlight.imf
and used to be called
J:\Projekte\BEWERBUNGEN\BBI Simulation\Eplus\Simulation Runs\Actuell\Daylighting Controls.imf

I shortened it to work around the problem. Since I re-ran, I don't have the last error report for you. The edd(?) file showed the last bit of the string missing.

Hope this helps...obviously not urgent as it's easily worked around.
