// End/Beginning of table. I do not consider this an error and
// will return a 0 in this case. To find out whether the End/Beginning
// of table was reached, use the class variable tblmarker. This
// will be set to 1 if EOT/BOT has been reached, 0 otherwise.

// provided for Alphanumeric fields but you have the source and
// can add the appropriate functions. I just haven't ever had to
// search by date or number yet!

// Due to the nature of C++, I have defaulted the last parameter
// of the search() function to use SEARCHFIRST. For this reason,
// all you need to do is the following call. If you wanted CLOSESTRECORD
// cust.custid.search(enterid, CLOSESTRECORD) would be the syntax.

// Previously you saw how to use read_rec(). That function will
// do a PXRecGet() and then do the appropriate PXGet..()'s.
// Sometimes, you only want to read a field or 2. If speed is a
// concern then use the method shown below because you don't
// have to read uneccessary fields.

// This is the standard error handler for PX_Buddy++. You can make it
// as involved as you like. Since I usually program with Vermont Views
// I have a pdxerr() that has windows that flash errors and have sounds
// etc. Since I don't know what you have, I just made a real generic
// model. pdxerr() does use the C++ property of default parameters.
// What this means is that you can ignore the 3rd (last) parameter
// if you use the prototype:
// void pdxerr(int, char *, int = 0);
// By using this, you never have to specify the 3rd parameter unless
// the error is fatal, which means either the problem must be corrected
// or the program will stop. You can see how I use this in the
// if (fatal) line.

Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
