Array logic

Hi Team,

I need to accomplish the below logic, but as we don't have array concept, could any one please help me in accomplishing the below logic by any way.

BF1= Blank

BF2=X

BF3= Blank

BF4=X

BF5= Blank

BF6=X

BF7= Blank

BF8=X

BF9= Blank

BF10=X

BF11= Blank

BF12=X

BF13= Blank

BF14=X

K=1

i = any numeric value eg.5

While K not equal to 0

{

If (BF[i]==X)

{

then New BFPeriod=i

k=0

}

End If

If ADAR =A

{

i=i+1

}

else

{

i=i-1

}

End wile

Thanks & regards,

Terry
