Error in subcript checking

[fm-117]

Describe the bug
There is a bug in PR #2004 (issue #400), the lower bound of a literal subscript is not the MinOccurs of the table but always 1.

To Reproduce
(Type)Cobol code that cause the bug : (if any)

       IDENTIFICATION DIVISION.
       PROGRAM-ID. TCOMFL06.
       DATA DIVISION.
       WORKING-STORAGE SECTION.
       01 tab1.
          05 max-val pic 99.
          05 oc1 occurs 3 to 10 depending on max-val.
             10 item PIC X.
       PROCEDURE DIVISION.
           DISPLAY item (1)
           DISPLAY item (20)
           GOBACK
           .
       END PROGRAM TCOMFL06.

The parser will report 2 errors, one on each DISPLAY which is incorrect. Only the second one is wrong.

Expected behavior
Check against the constant 1 and report an error only on the second display in the example.
