Hi everybody,

I would like to check wether my database exists or not before (re)creating it.
The name of that db is a string variable which depends of an other string variable and I use the support function @fileexist. My problem is that @fileexist always returns 0, saying the file does not exist even if it's actually existing.

More precisely, my code is as follows

Code: Select all


%name1="name1"
%name2="\\...\name2{%name1}.edb"

if @fileexist(%name2) then
     dbdelete %name2
     dbcreate %name2
else
     dbcreate %name2
endif

Does someone have any ideas ? I suspect that it's because EViews is actually not replacing {%name1} by name1 when creating %name2.

Thanks a lot !

Braces inside quotes will not be replaced. Do this:

Code: Select all


%name1="name1"
%name2="\\...\name2"+%name1+".edb"
