end
-- close a block statementend
is a keyword which, depending on the context, is
parsed as one of the following keywords:
end_case
, end_for
, end_if
, end_proc
, end_repeat
, end_while
Each of the keywords proc
, case
, if
, for
, repeat
, and while
starts some block construct in
the MuPAD language. Each block can be closed with
end
or with the corresponding special keyword end_proc
, end_case
etc.:
>> f := proc(a, b) local i; begin for i from a to b do if isprime(i) then print(Unquoted, expr2text(i)." is a prime") end end end:
>> f(20, 30):
23 is a prime 29 is a prime
The parser translates end
to the
appropriate keyword matching the type of the block:
>> expose(f)
proc(a, b) name f; local i; begin for i from a to b do if isprime(i) then print(Unquoted, expr2text(i)." is a prime") end_if end_for end_proc
>> delete f:
end
is a new keyword.
