The blink samples are generated by a script. They all use a certainly named 
port pin.
Once a user complained that the blink sample did not work. It was due to a 
read/modify/write problem on a certain chip, which actually could only drive 
3.5mA on the standard pin. There were solutions discussed, including to have 
different blink samples which use a per-chip selected pin that can drive 25mA. 
That would have been a huge amount of work for a very small effect. So the 
solution chosen was to just recommend a low current LED for all samples.

Hi Sunish
Thanks for your fast reply. I have three questions ( written in red).
xx -- In the datsheet on page 40 I see some configuration-bits but the register 
has no name. Is it still possible to use those bits?

pragma target clock 4_000_000      -- oscillator frequency
--
pragma target OSC      INTOSC_NOCLKOUT           -- Int osc, no clockout 
………..>>>>> in the datasheet and in the library16F505:  I can't find 'noclkout'
pragma target WDT      DISABLED                  -- watchdog
pragma target MCLR     INTERNAL                  -- internal reset
--
-- A low current (2 mA) led with 2.2K series resistor is recommended
-- since the chosen pin may not be able to drive an ordinary 20mA led.  
……….>>>>>> in the datasheet the pin can deliver 25 mA/that is enough for a 
standard led

--Best regards,
Peter

HiI never worked with small PIC's.I want to use the internal oscillator of the 
16F505.Is it correct I need to change in the library 16F505 in the oscillator 
part: 
pragma fuse_def OSC 0x7
in
pragma fuse_def OSC 0x4
Best regards,Peter
