Matrix: LET variable unkown

[Koch013]

I receive the following error when running the test for Matrix:

We received the following error when we ran your code:
./zcl_matrix.clas.abap[79, 5] - "lv_start" not found, findTop (check_syntax) [E]
./zcl_matrix.clas.abap[82, 5] - "lv_start" not found, findTop (check_syntax) [E]
abaplint: 2 issue(s) found

Looks like to be the same error as in 148 but this time for VALUE

Here's my code:

thanks 👍

reproduced as

DATA result TYPE STANDARD TABLE OF i WITH DEFAULT KEY.
result = VALUE #(
  LET lv_start = 2 + 2 IN
  FOR i = lv_start UNTIL i > lv_start * 2
  ( lv_start ) ).

Error

Error: ValueBodyTranspiler, unknown Let "LET lv_start = ( index - 1 ) * lv_columns + 1 IN"

probably fixed in abaplint/transpiler@b5cbad0
