You can enter two IF statements in syntax:
IF (AGE LT 365) newvar=[formula 1]
IF (AGE GE 365) newvar=[formula 2]
You can also combine the two in a single formula with two logical
conditions:
COMPUTE newvar = (AGE LT 365) * [formula 1] + (AGE GE 365) * [formula 2].
In this variant, each logical condition will equal either 0 or 1, and
therefore only one formula will be computed for each case.

Subject: compute variable using if statements
guys sorry i know this is a basic question but i cant seem to remember how i
did this last time. i have one variable, age in days, and another variable,
rate. i want to create a formula for rate using values fo other variables.
but i have a different formula for when age is < 365 and a different one
when it is >= 365. In Compute Variable, there is an option for me to select
an 'if statement'. But how do I enter in two if statements, with the
different formulas for each. or is there a kind of syntax i can use? thanks
so much!
