16F628 vs 16F628A oscillator

Hello,
I am just a bit confused about setup_oscillator. This function does not work with 16F628 (I get "undefined identifier -- setup_oscillator") but it works with 16F628A.

I want to achieve internal 4MHz oscillator:
INTRC_IO fuse and setup_oscillator(OSC_4MHz);

Or is the oscillator config set automatically by "#use delay(clock=4000000)" ?

My compiler is v3.242
Cheers guys.

This thread shows how to make your own setup_oscillator() function
that will work with the 16F628:

Hello,
thanks for the hint. I was trying to search the forum but it didnt lead me to the thread you posted (i was looking for "16F628" not 627).

Have a nice sunday,
