INPUT - Délimiteur LF non reconnu - solution TextStream objet
Bonjour à tous,
La commande INPUT réserve bien des surprises... La dernière en date, elle n'interprète pas LF comme le caractère de fin de ligne. Il existe de nombreux posts sur le sujet et l'explication donnée est que ce type de fichier est celui du monde NON WINDOWS.

Ici extrait ci-dessous
- a LF without a CR is UNIX, Linux, AmigaOS and now Mac -
- since Mac OS X.
- Until Mac OS version 9 the Mac was usung a single CR without
- a LF. Same for the Apple II.
- CR+LF is Windows, DOS, OS/2, CP/M, Atari TOS.
Citation:
For the old teletypes you needed both CR + LF.
In the mid-seventies I saw a program using a teletype as "printer".
They used multiple CR without a LF to write columns.
With a teletype you had to send first the CR (carriage return) then
the LF (line feed) due to the latency time of the mechanical equipment.
If you did it the other way, the first character of the new line was
printed somewhere to the right, not in the leftmost position.
