It can get frustrating trying to track down information when one is
learning.  I'm perusing through the "Hi-Tech C 10/12/16" manual as well as
the datasheet for the 16F690.  I'm trying a couple projects in C on the "Low
Pin Count" Microchip board.

I'm trying to understand an example that flashes a couple LEDs on the board.
I can follow the C source pretty well, I can edit the code and recompile to
control different LEDs and so on.  It's the configuration bit setting that
I'm trying to understand.

My program uses the following config setting:

__CONFIG (INTIO & WDTDIS & MCLRDIS & UNPROTECT);
//Internal Clock, Watchdog off, MCLR off, Code Unprotect

Since it is commented, I can see what is happening.  It's the terminology
itself that I haven't found a reference for.  I was playing around with the
MCLR setting by temporarily deleting it from the code, and controlling MCLR
via the buttons in MPLAB.  (I wanted to prove to myself that if MCLR is
disabled as above, the buttons have no effect - they don't.)  

If I were writing this program from scratch, how would I know, and where
would I find 'DIS' for 'MCLRDIS' ?  I searched on the web, and I see that If
wanted MCLR enabled, the command is 'MCLREN'. No mention that I can see in
the manual.

Since it's apparently related to the compiler, I don't expect to see the
reference in the datasheet, but the compiler manual itself seems devoid of
explanation.

Am I missing something in understanding where to find answers?
