I personally learned by editing lvdm and a51 that were included in the SA:MP Download package (a51 no longer included). And there is no set time to how long it takes to learn, since you learn something new everyday! Also, just search the forums for the thousands of threads like yours. There have been multiple listed ways of learning.

pawn Code:

strmid(stat, tmp, 0, sizeof(stat), sizeof(stat));

Extracts the data inside "tmp" array into the "stat" array, starting at position 0. - https://sampwiki.blast.hk/wiki/Strmid
