I was wondering, in terms of 1)Speed and 2)Good Form...which is preferable.

lntemp = iif(switch==.t., lntemp+1, lntemp)

OR

if switch == .t.
lntemp = lntemp + 1
endif


Obviously, its nice to have just one line, thus the appeal of the iif. But it seem redundant to continually assign lntemp to itself, especially if the majority of the time 'switch ==.f.' Or is the compiler smart enough not to reassign a variable to itself?

For Example:
lntemp = 1
* a trillion lines of...
lntemp = lntemp

i mean, assuming it takes only 1ns to assign a variable, that's either 1ns or ~17minutes
