Wasn't it a linker limitation originally? 6 characters per name, plus C name mangling prepended an underscore for some reason, so _creat was the longest you could have at the linker level.

There is the "localtime" call in V7 (at least whatever copy I could grab off github), which is way above 6 characters.

And as for V1, there is the "putchar" function.

Was there?? I thought "putchar" was a macro for fputc(c, stdout), but I haven't checked V1. Rules for macro names would be different from those for linker symbols.
