GSUM returns an aggregate sum statistics for an input variable.
The number of values that are aggregated is determined based on the frequency of the input variable.

SYNTAX:

GSUM(Cx)
where :
Cx is a input conditional variable x.

NOTES:

The input variable frequency should be less than the result variable frequency. It makes sense to aggregate 5 one-minutely values into a 1 five-minute variable, but not the other way around.

EXAMPLES:

V6031 = GSUM(C6000)

where V6000 is a 15 minute variable, and V6031 is an hourly variable.
