Percent Rate of Change?

["BobR" <bobrabcd@xxxxxxxxxxxxx>]

What does the MetaStock PERCENT rate of change convert to in easylanguage?
roc(close,12,%) in MetaStock = what in easylanguage? 

Likewise what does the MetaStock POINT rate of change convert to in ELA?
roc(close,12,$) in MS = what in ELA?

thanks,
bobr
