Fail to open DSN with TCL due to both "dot" and "space" in the file name

Gelzone

I try both Menu "File::Open::Design" and MenuCommand "57601" to open my file with tcl but fail.

The file name is "<project folder>/test_M.2 test1.DSN" and the error message shows something like "<project folder>/test_M.2 not found".

And I try to remove the "dot" (keep the "space"), the command can open the DSN file successfully.
Another experiment that keeping "dot" but remove "space" also works well.

So I think this file not found issue will occur when both "dot" and "space" exist in the file name.

    Space is a field separator at operating system level.

    A lot of problem occur if usinf this caracter in pathname or name.

    My advice is to use ONLY:

    a to z

    0 to 9

    underscore (_)

    dash (-)

    and no other caracters.

    By the way, be aware of file pathname length, operating system like windows handhle badly verry long name (in the past, file pathname were not or badly handheld is more than 255)

    Thanks for reply.

    The DSN name is following my company's rule so I think it's not that easy to change the format. And the DSN name will affect the netlist content, so I ain't gonna to change it to a temp name.
