You don't have to do that if you have your own way of generating the 
breaktable(name){raw, eng, ...} that the IOC can load (see 6.11, although I 
suspect you have an older copy of the AppDevGuide with different numbering).  
Note that you can load a .dbd file containing break-point table data using 
either dbLoadDatabase or dbLoadRecords, and the table data values can be space 
or comma-separated.

The makeBpt program described in 6.15 is useful if the calibration data you 
have needs to be re-sampled to provide conversions with an acceptable error, 
bearing in mind that the IOC code gives you values taken from a straight line 
drawn between adjacent data points.  You wouldn't need to run makeBpt manually 
since that's all taken care of by the build system when you tell it
	BPTS += bptXxx.dbd
and give it the data table as described in a file named bptXxx.data.
