What is the problem in running the simplest scripts?

Question

cmd/bat

I write a batch file to save time, as I study python and open several programs at once in any session.
Here is the code:

call "C:\Users\Nananan\Desktop\IDLE (Python 3.8 32-bit).lnk"
call "C:\Users\Nananan\Desktop\ A_Byte_of_Python_2.01.pdf"
call "C:\Users\Nananan\Desktop\PyCharm Community Edition 2020.1.2.ink"

Then I save it as bat and open the file via cmd as C.../Desktop/filename.bat
The standard IDLE opens, but the two remaining paths (the book in pdf and PyCharm) give me that '' is not an internal or external command , executable command or batch file'' - for PyCharm and simply ignore the pdf file without throwing an error in output.

Question:

What could be the problem?

a) Incorrect syntax (using call is wrong. But I tried other operators and there is no result)
b) Problem with the path in the case of the book and PyCharm

Answer 1

Use start instead of call
