Possible bug? Unable to enter a comma in response to INPUT

[DSMan195276]

This behavior is correct, it has to do with how

Input

allows entering multiple variables at once (with their values separated by a comma). Because of that, when using

Input

with a string on its own you cannot include a comma in the value. You should use

Line Input

instead, which basically works exactly like you want - it reads an entire line of input text into a single string, with no limitations on commas or etc. being in it.

There is a note about this behavior on the Wiki, it goes into a bit more detail:
