#1751 — How to get the OS path of a file?

I have a PS file (main.ps) in which I include an EPS file (image.eps) with

save
%%BeginDocument: image.eps
%(image.eps) run                (1) or
(path/to/file/image.eps) run    (2)
%%EndDocument
restore

Method (1) works in editor SciTE (path of file image.eps can be
found from ghostscript), but in DOS shell (command.com, Windows 7) I get  
an error message
(No such file or directory) from ghostscript (v.9.10). Method (2) works in  
both cases.

If I wanted to copy the two files to another place I would have to
change the path/to/file in main.ps **by hand**.

Now my question: Does anybody know how to get the path of a file  
**automatically** (from the OS) as a string  that I could use in main.ps?

You could define the path and the filenames separately and 
concatenate them before using. 

I do this in my interpreter's init.ps to locate other data files.
DATA_DIR is just a string containing the pathname.

/strcat {
    2 copy
    length exch length exch 1 index add % a b an bn+an
    string dup 0 6 -1 roll putinterval % b an str
    dup 4 2 roll exch putinterval % (ab)
} bind def

DATA_DIR
(/err.ps) % my path string doesn't end in a slash, so need it here
strcat
run
