How to set zero to array variable in OTL Fast formula

Summary:

Hi Experts,

I want to ensure that nothing is printed on the timecard screen, not even zero (0).

The variable responsible for this is an array of type EMPTY_NUMBER_NUMBER.

Initialization:
out_measure_reg = EMPTY_NUMBER_NUMBER

Current Issue:
Using the following statement results in printing 0, which I want to avoid when the else if condition is met:

else if (tcRecPosition_next <> 'END_DAY' and tcMeasure > 0) then
(
out_measure_reg[nidx] = 0 /* Calculating hours at the last record of the day; return remaining records as zero */
)

Question:
Is there a way to achieve this where nothing is printed on the timecard screen, not even zero (0)
