INSPECT statement (BEFORE / AFTER phrase)

[Jonathan Beit-Aharon]

Hi there,

If you look at the INSPECT statement at 
https://www.ibm.com/support/knowledgecenter/SSQ2R2_9.5.1/com.ibm.ent.cbl.zos.doc/PGandLR/ref/rlpsinsp.html
  you might notice that it is allowing repeating BEFORE | AFTER phrases 
("phrase 1").

Assuming they are correct, and given data such as:
       DATA DIVISION.
       WORKING-STORAGE SECTION.
       01 S1  PIC X(23) VALUE "AbAbAcAcQrAbQsTrAAbAb".
       01 S2  PIC X(23) VALUE "AcAcAbAcQrAbQsTrAAbAb".
       01 SA  PIC X(23).
--
       01 N1R.
           03 N1LABEL PIC   X(3)  VALUE 'N1='.
           03 N1      PIC  S9(2)  VALUE 0.
           03 N1SEP   PIC   X(2)  VALUE '+,'.

one expects the statement (sentence, really)
       INSPECT S1 TALLYING N1 FOR ALL 'Ab' BEFORE 'Qr' BEFORE 'Qs'.
to be parsed.

FWIW, I ran into this while trying to upgrade from my Open COBOL version 1, 
downloaded in 2009, to the latest (well, almost... downloaded in August 2019).

Thanks and regards,
