[photran] Re: managed make from command line

[Daniel Harenberg <dan.harenberg@xxxxxxxxxxxxxx>]

Hi David,

thanks for your quick reply. The folder does exist, so this doesn't seem 
to be the reason. The line of code that the error is referring to (293) 
reads

open(unit=100, file='model_output/value.txt', status = 'replace')

Again, this does work flawlessly when executed from within Photran. Is 
there any other information that I can supply? I am very greatful for 
any help.

Best regards,

Daniel
