Background:
Currently, the Natural statement READ...BY ISN does NOT support the TO clause.
One must code READ...BY ISN...FROM...THRU/ENDING AT.
Yet the Read Logical (eg. READ...BY PERSONNEL-ID) supports FROM and TO.
Enhancement Request:
Allow the READ...BY ISN to support FROM and TO.
Justification:
1. Syntax Consistency
2. Intuitive
We are looking into this again. We will implement it on the next upcoming releases.
READ BY ISN FROM THRU is the valid option to use, the "extra" record should be handled by the PROGRAM.
We will introduce soon READ DESC By ISN to support other scenarios.
