Continued from last post

In a range evaluate type code line like the one we are considering, Excel VBA seems to do the following ( simplified ) ( refs *** )

Excel will have an output "window" ( this could be considered as an output table or output array ). The dimensions of this will be that rectangle that allows all used ranges in the formula to be fitted in,
There are some complicated ways in which Excel handles the situation of ranges of varying size, ( http://www.excelfox.com/forum/showth...on-and-VLookUp ) but for a simpler case of all ranges having the same size, ( in terms of "width" and "depth" ) , as we have, Excel VBA will "expand" its "output window" to this sort of thing:


Excel VBA will do its normal "along the columns, down a row, along the columns…" type thing, in any "Evaluation run". In our case this will mean that it does an evaluation at each row, going down the rows. This is what Excel VBA does in order to fill that last window of cells, ( I am just showing the first 7 of 40 similar formulas as the full list is to big to fit in a forum post )
=IF(ISNUMBER(0+SUBSTITUTE(SUBSTITUTE(A2," ",""),",","")),IF(LEFT(A1,4)="2018",TRIM(A1&" "&A2),""),IF(LEFT(A1,4)="2018",A1,""))
=IF(ISNUMBER(0+SUBSTITUTE(SUBSTITUTE(A3," ",""),",","")),IF(LEFT(A2,4)="2018",TRIM(A2&" "&A3),""),IF(LEFT(A2,4)="2018",A2,""))
=IF(ISNUMBER(0+SUBSTITUTE(SUBSTITUTE(A4," ",""),",","")),IF(LEFT(A3,4)="2018",TRIM(A3&" "&A4),""),IF(LEFT(A3,4)="2018",A3,""))
=IF(ISNUMBER(0+SUBSTITUTE(SUBSTITUTE(A5," ",""),",","")),IF(LEFT(A4,4)="2018",TRIM(A4&" "&A5),""),IF(LEFT(A4,4)="2018",A4,""))
=IF(ISNUMBER(0+SUBSTITUTE(SUBSTITUTE(A6," ",""),",","")),IF(LEFT(A5,4)="2018",TRIM(A5&" "&A6),""),IF(LEFT(A5,4)="2018",A5,""))
=IF(ISNUMBER(0+SUBSTITUTE(SUBSTITUTE(A7," ",""),",","")),IF(LEFT(A6,4)="2018",TRIM(A6&" "&A7),""),IF(LEFT(A6,4)="2018",A6,""))
=IF(ISNUMBER(0+SUBSTITUTE(SUBSTITUTE(A8," ",""),",","")),IF(LEFT(A7,4)="2018",TRIM(A7&" "&A8),""),IF(LEFT(A7,4)="2018",A7,""))


Excel VBA will effectively make 40 formulas and place in the "output window" the result of the evaluation of those formulas
The full demo code in the next post includes a code line to put in all 40 formulas in an arbitrary 40 "deep" x 1 "wide" range ("J5:J44")
