Hi In development languages I'm used to defining various constants values in the files, but I couldn't find such in Therion Have you considered adding this feature? For example I use the cave name in several places in the .th and .thc files. Then for the next cave I usually copy the template and change the name in all the places it is mentioned. This will be easier to do with a constant value that is changed only in one place. Something like this: === in TH files === DEFINE %NAME%='My cave name' survey %NAME% -title "%NAME% cave located somewhereПещера %NAME%..." ... input %NAME%.th2 endsurvey === in THC files === layout ZZZ map-comment "The %NAME% is a very nice cave, etc, etc" endlayout export map -projection extended -output %NAME%-xelev.pdf export map -projection plan -output %NAME%-plan.pdf So you can change the DEFINE %NAME% only at the begining of the file and the value will be reflected when compiling in every place the %NAME% is used. Or am I too picky Vladimir ------------------------------------- Mail.BG: Безплатен e-mail адрес.
