Define every MQL4 variables, functions?

Hi all,
I want to find out Mathmax, Mathexp, ArrayRange, iVolume, MODE_POINT,. . . .
Where can I find define for every MQL4 variables, functions?
Thanks .

open the metaEditor, then click on the Help tab at the bottom, then click on the sync tab at the top of that lower panel that pops up, then click on search at the bottom of the panal that pops up to the right

Or you can go to mql4.com and click on documentation. That's what I use for my reference

I know this doesn't directly answer your question but this is also useful:

press F1 when the cursor is on the keyword (function name, constant, whatever) in metaeditor.

Hi all,
I have just found some files define for every functions.
