reads lines from the standard input,

If the line contains an expression or list of expressions,
then the line is evaluated and the results are printed.
If a line does not contain a complete statement,
then a secondary prompt is displayed and
lines are read until a complete statement is formed or
a syntax error is found.
So, one way to interrupt the reading of an incomplete statement is
to force a syntax error:
adding a
.B ';'
in the middle of a statement is a sure way of forcing a syntax error
(except inside multiline strings and comments; these must be closed explicitly).

At the very start,

displays the values of all the expressions in the remainder of the

The primary prompt is the value of the global variable
.BR _PROMPT ,
if this value is a string;
otherwise, the default prompt is used.
Similarly, the secondary prompt is the value of the global variable
.BR _PROMPT2 .
So,
to change the prompts,
set the corresponding variable to a string of your choice.
You can do that after calling the interpreter
or on the command line
(but in this case you have to be careful with quotes
if the prompt string contains a space; otherwise you may confuse the shell.)
The default prompts are "> " and ">> ".
