Labels are not the reason for basic line numbers, they are only a side effect such to say. In addition, FORTRAN line numbers were arbitrary, more like numeric labels than line numbers. And in high school, we had a "modem" that let us dial into Dartmouth's computer, and experience this wonder first hand. I remember the fairly big problem of wanting to add a line between line 24 and 25, when there was no way of renumbering lines . Connect and share knowledge within a single location that is structured and easy to search.
This was a prototype, implemented as an experiment while the teletype-based interface that the language was being designed for was still being developed. That DTSS had a rudimentary IDE, which was nothing more than an interactive command line. The original editor for DOS was a wonderful utility called edlin. You could only edit a single line. Your program was stored in memory and you would type in single line commands to edit single lines. Before there was such a thing as a VDT , we old-timers programmed on punch cards.

Writing a label takes more memory, first in the location, where that label is defined, then in any jump command. I'd guess it comes from assembler, where each instruction has an address which may be jumped to by another instruction. They originated in FORTRAN, from which BASIC was derived. However, in FORTRAN only lines referenced by other lines needed numbers. In BASIC they had a secondary use, which was to allow editing of specific lines. That's actually how I learned to program - editing by retyping.
High 51F. Winds SW at 10 to 20 mph. Light rain developing after midnight. Did you mean, that it was really hard to write in spite of the fact that it's so stupid? I think, it'd give a better idea of what kind of person you are. Fortran used both numeric target labels on the left (col 1-5) and left a reserved block on the right (73-80) for sequence or comment.

Winds SW at 10 to 15 mph. Considerable cloudiness. Occasional rain showers later at night. Winds SSW at 10 to 15 mph. Low 32F. Winds W at 10 to 20 mph. Some light rain is likely.
Showers early becoming a steady light rain later in the day. High 48F. Winds SW at 10 to 15 mph. In Mother's day, there are also some programming language jokes.. I think the question was about languages where you had to type in the line numbers yourself. I agree line numbers that are displayed automatically by the editor are very useful .

But as soon as I got my hand on a Vax with it's Extended BASIC, I was so happy to never see a line number again. Back in the fifties, when high programming languages were in their early beginnings, there were no terminals, no editors, no monitors , just card punchers and readers and printers . Later, tape was introduced, but that's another story. On the first interfaces BASIC was available for, there was no shiny editor, not even something like vi or emacs . You could only print out your program on the console and then you would add new lines or replace them, by giving the appropriate line number first. You could not navigate through the "file" with the cursor like you are used to nowadays.
Fortran also qualifies. A few showers early with overcast skies late. Mostly cloudy skies. High 49F. Winds SSW at 5 to 10 mph. Steady light rain in the evening. Showers continuing late.
This question needs to be more focused. It is not currently accepting answers. There's actually a problem because that results in home, sweet, home, sweet, home etc. Cloudy with occasional rain showers.
Showers early becoming a steady light rain late. Low 44F. Winds SW at 5 to 10 mph. Low 43F. Winds SSW at 10 to 15 mph. Its name is a reference to the traditional looping 'Hello world' program written by beginner programmers. As with all programming languages, we see the prefernces of the programmer in the various code examples that have been offered. This is probably Pascal, because in C there is no repeat..while loop.
Low 42F. Winds S at 5 to 10 mph. It received more prominent vlog, blog, and print news coverage when Kevin Olson displayed the first ever American showing of ANSI art in a physical art gallery. Heck we could go nuts and read hex code that corrisponds to the ASCII codes of each of the characters, and read that out of a seperate data file.... VIEWIC is cool because "VIEWIC Identifies Ellipsis When It Can" contains ellipsis. Also, it's antecedent-contained ellipsis, so it forms another infinite loop. Back in the day you didn't have a 2 dimensional editor like emacs or vi.
High 46F. Winds SW at 10 to 15 mph. A few showers early with mostly cloudy conditions later in the day. High 49F. Winds SW at 5 to 10 mph. Mostly cloudy during the evening.
