using debugger to open file for program to read data in, is not seeing that file

[userx-bw]

simple little program that opens a file then reads its contents, when using the debugger asknig for a filename it does not see that file in the same dir it is in, ../Debug/
hard code it in and it still does not see the file.

open a seperate terminal then goto where program is located along with the file, run it and it sees and opens then reads the file.

how to get the debugger to do the same?

Have you set the args for the program run by the debugger?

MainMenu/Project/Set program arguments...

[userx-bw]

OK in the "program arguments' text box.
I added absolute path and file name, now I got a figure out how to show values and show execution line steps, so I can follow it around in the loop.
