    The program/ header file contents

    Karl this is albeit your program, in the program that you wrote for me
    I learned quite alot, i didn't realise I could return NULL for
    instance or even use functions without first declaring them, but this
    is where I'm encountering resistance, as all the bool functions are
    compiling with the error: local function definitions are illegal. I've
    never used using namespace std before and was wondering if you had
    created a header file in conjunction with the program you wrote. Your
    program executed perfectly.
    Any one else who has spotted something amiss please post back.

    Thank you for your kind attention in this matter.

    A strong indication that you have messed up your { - } pairs somewhere.

    where is the opening '{' for this '}'
    Searching the source backwards, here it is:
    [color=blue]
    > if(len<103){[/color]

    even though the indentation level suggests, that you wanted
    to match this } with the one in
    [color=blue]
    > switch(cstring[0])
    > {[/color]

    But the compiler doesn't care about indentation :-)
    The compiler only cares about the stream of tokens.
    And the stream of tokens indicate that this '}'
    matches the '{' in the if( len<103){


    .....
    Same thing in a lot of other places.

      You sound like you are continuing a discussion from a previous thread
      - I haven't seen the previous thread.

      Opening brace ^

      [Sorry if the indenting has gone wrong here, I have replaced your tabs
      with spaces to (hopefully) ensure the ^ symbol lines up where I want
      it.]

      > prnfile<< "Invalid:";

      No closing brace here where I presume from your indenting you intended
      one.
      [color=blue]
      >
      > return false;

      This closing brace ends the if(len<103) block.
      [color=blue]
      >
      > return true;
      > };[/color]

      This closing brace ends the switch(cstring[0]) block. ie we are still
      in the CRecordvalidlen gth function, and the next thing that happens is
      ....
      [color=blue]
      > ////////////////////////////////////////////////////////
      > bool Drecordvalidlen gth(ofstream& prnfile, char* dstring)
      > {[/color]

      .... a function definition, which is not allowed inside another
      function. All the function definitions below are still local to the
      CRecordvalidlen gth function hence illegal. Put in a closing brace for
      the if(len<103) block and that problem is fixed.

      You're missing a closing parenthesis, you need
      if( !CheckDigitForC ustomerCode( check_code ) ){
      ^
      [tabs replaced with spaces again]

      The identical mistake (cut-and-paste gremlins?) is in
      ProcessDCustome rCode and ProcessIRCustom erCode.

      <snip the rest of your code>

      Having made those changes, I still get lots of errors (42 in fact, how
      nice) but without the context of the discussion that led you to this
      point, I don't know which you might need help with.
