I need to repeatedly check within which of predefined time periods the current moment is. Since this affects overall performance (but is necessary), I am trying to see whether there is an alternative to a compound if to speed this up.
t1, t2, t3, ... , t7 -- time interval boundaries in seconds c - current time in seconds
if c < t1 then do1 else if c >= t1 and c < t2 then do2 else if c >= t2 and c < t3 then do3 ... else if c >= t7 then do8 end if
Anyone any ideas? I seem to have a "writer's block" :(
You could try switch:
switch case c < t1 do1 case c < t2 do2 case c < t3 do3 ... case c < t8 do8 end switch
Note there are no breaks between case statements so the script should run through all options until it finds a valid equation.

Scott, but your switch statement is not equivalent to the compound if above. For example, if c < t1, the if's will execute do1 whereas your switch will do do1, do2, ... do8. That's wrong.
I tested timing of switch with double conditions versus compound if (in other words, just replacing if's with case's) and they clock to be the same on my G3/400.
