3.1.2 The SINGULAR prompt

The SINGULAR prompt > (larger than) asks the user for input of commands. The "continuation" prompt . (period) asks the user for input of missing parts of a command (e.g. the semicolon at the end of every command).

SINGULAR does not interpret the semicolon as the end of a command if it occurs inside a string. Also, SINGULAR waits for blocks (sequences of commands enclosed in curly brackets) to be closed before prompting with > for more commands. Thus, if SINGULAR does not respond with its regular prompt after typing a semicolon it may wait for a " or a } first.

Additional semicolons will not harm SINGULAR since they are interpreted as empty statements.
