end -- close a block statement

Introduction

end 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

Example 1

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:
