The program/ header file contents

P: n/a
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.

You can't :-)

A strong indication that you have messed up your { - } pairs somewhere.
#include <iostream>
#include <iomanip>
#include <fstream>
#include <cstring>
#include <cstdlib>

using namespace std;

struct crecord {
long customercode;
char customername[21];
char customeraddress[61];
double customerbalance;
double creditlimit;
};

struct irrecord {
long customercode;
long partnum;
long issue_rec;
};

struct drecord {
long customercode;
};

////////////////////////////////////////////////////////////
bool IRRecordvalidlength(char* record)
{
int len;

switch(record[0])
{
case'i':
case'I':
case'r':
case'R':
len= strlen(record);
if(len<17)
return false;
break;
}

return true;
};
The ';' is superfluous. Remove it.
////////////////////////////////////////////////////////////
bool CRecordvalidlength(ofstream& prnfile, char* cstring)
{
int len;

switch(cstring[0])
{
case'c':
case'C':
len = strlen(cstring);
if(len<103){
prnfile<< "Invalid:";
prnfile<< cstring << endl;

return false;
};
where is the opening '{' for this '}'
Searching the source backwards, here it is:
if(len<103){
even though the indentation level suggests, that you wanted
to match this } with the one in
switch(cstring[0])
{


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.

Thank you for your kind attention in this matter.
You sound like you are continuing a discussion from a previous thread
- I haven't seen the previous thread.

<snip to the cause of your "local function definitions" error>
////////////////////////////////////////////////////////////
bool CRecordvalidlength(ofstream& prnfile, char* cstring)
{
int len;

switch(cstring[0])
{
case'c':
case'C':
len = strlen(cstring);
if(len<103){ 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:";
prnfile<< cstring << endl;
No closing brace here where I presume from your indenting you intended
one.

return false;
};
This closing brace ends the if(len<103) block.

return true;
};
This closing brace ends the switch(cstring[0]) block. ie we are still
in the CRecordvalidlength function, and the next thing that happens is
....
////////////////////////////////////////////////////////
bool Drecordvalidlength(ofstream& prnfile, char* dstring)
{
.... a function definition, which is not allowed inside another
function. All the function definitions below are still local to the
CRecordvalidlength function hence illegal. Put in a closing brace for
the if(len<103) block and that problem is fixed.

<snip to the other problem my compiler picked up immediately>
bool ProcessCCustomerCode(ofstream& prnfile, char* record)
{
char check_code;
long checkcode;

strncpy(check_code, &record[2], 5);
check_code = '\0';
if( !CheckDigitForCustomerCode( check_code ){


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

The identical mistake (cut-and-paste gremlins?) is in
ProcessDCustomerCode and ProcessIRCustomerCode.

<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.
