search a number of on array
Posted: Fri May 27, 2022 08:13 PM

I have an array created with

AaDd(aFrequeMax[nRuota],{massimo, &num})

then I have a number for a sample 42 and the nWheel 1

I must found the number 42 on aFrequeMax [nWheel] and return me the second element of this array

How I must make it ?

I tried with
AEval( aData, { |a| If( (a[1] = numero ), nFrequenza:=a[2] , nil ) } )

sample nWheel = 1

I have to find out if my number is in the first column, if it found it, return the value for the second column

For a sample my number is 66 it must return 594

Code (fw): Select all Collapse

function ArrLookUp( aArray, nSeek )

   local nAt
   
   if ( nAt := AScan( aArray, { |a| a[ 1 ] == nSeek } ) ) > 0
      return aArray[ nAt, 2 ]
   endif
   
return nil
