Subject: path string
Dear Tutor.
I am trying to create unsuccessfully source path as a string 'str7' in part_1
of the code below, to be used in part_2 of the code.
When I define the source path explicitly in part_2 of the code (#sourcePath =
r'H://TCVFLDAT'), the code works right.
How else could I find the path in part-1 and use it in part 2?
##
Here is my code:
