Hi Emil,
 your returned lines will always include the terminators, therefore you will never get an empty line to terminate with. This is why I captured the line string before skipping the termination chars.

yes Charles ,

my source code may contain an empty line and that does not mean the end of string (source code) , so i need
an other way to  terminate the loop.

[Emil_halim]

I am thinking in c language , char* is a pointer to the buffer of returned string and if is null that will end the loop ,

what is your opinion ?

[Charles Pegge]

You can record the ascii value of the terminating character, as a global state variable possibly, and test for zero to exit the line-reading loop.

 I use global state variables in the compiler to hold parsing data like word-position word-ascii, next- word-position, word-length.
