Chapter 9 Data Tables 259<br />

Messages for Data Tables<br />

If you also send the Run Formulas command to data column, the evaluation is done at the time of the<br />

command, but it does not suppress the scheduled evaluations that are pending. Therefore, formulas might<br />

end up being evaluated twice if you also send the command to the data table. Being evaluated twice might<br />

be desired for formulas that have random function in them, or it might be undesirable if they depend on<br />

randomization seeds being set. If you use random numbers and use the Random Reset(seed) feature to<br />

make a replicable sequence, then use the Run Formulas command, since it avoids a second evaluation.<br />

Note: Starting in version 6, all platforms send a Run Formulas command to the data table to assure that<br />

all formulas have finished evaluating before analyses start.<br />
