Yes, this solved the problem. Never realized till now the difference between "END" and "SYSTEM" statements which I have been using interchangeably all these years. Thank you for the quick response.

I am back again. While the "pipecom.h" library provides a solution, it captures all the file names in the folder meeting the specified criterion. Having a folder with hundreds of files will require creating a huge string array to store all the file names in the program.

The original code using DIR$ function of BASIC fetches only one name at a time, which is a more elegant solution.

I wonder if the "while (!feof(stream))" statement be pulled out of the library so that it provides only one file name at a time and returns a nul when all the files are covered.

Thanks


F$=DIR$("*.LL1")

DO WHILE F$ <> ""

    CNT$ = LEFT$(F$, 4)

    OPEN CNT$ + ".LL1" FOR INPUT AS #1
    OPEN CNT$ + ".LL" FOR OUTPUT AS #2

    F$ = DIR$

LOOP

My old BASIC code that was working with 32-bit QBASIC compiler now shows error in QB64 on the following line with DIR$ function. Is there any way to walk around this issue?

F$=DIR$("*.LL1")
