That sets them all to digital, but not definitely outputs.

Write zero to the TRIS registers as well, to guarantee all the pins are set to output mode.

Turn off any comparators as well, they conflict with digital modes.

Pins set to analogue will still work as digital outputs when set to output. However, a big gotcha is they always read as zero so RMW operations can produce strange results.

That's not been an issue for a great many years (basically the 16F628), the default now is comparators OFF.

If in doubt, set the pins using the MCC, which the OP is probably using to set the config fuses anyway? (I certainly do) - then either use it 'as is', or cut and paste the parts you want to your main code.
