Maybe somewhat obvious but...
Make use of operator return values
Keep in mind that the assignment operator returns a value!
For example, if you want to add y to x and then check if x is greater than something, you can do
if((x+=y)>2525<x+=y)
instead of
x+=y
ifx+=y;if(x>25)
Or maybe you want to find the length of a string after trimming it:
strlen(s=trim(s))
Rather than
s=trim(s)
strlen;strlen(s)
