Something?Oops! is a simple esolang by User:A. The syntax is as follows:
Statement: "<identifier> <identifier>?Oops<variable>" Identifier: A nonnegative integer or a variable Variable: "!" or "?" or "." or ","
A statement of the form "A B?OopsC" stores A + B in C.
? is a special variable in that reading from it produces input from the user rather than ?'s value, thus making ? effectively read-only as a variable. Likewise, . produces output, and though it can be used as a normal variable, anything written to it is also output to the screen. , is also special: it's the instruction counter. In fact, only ! is a "normal" variable at all.
