Add the hability to process NULL values in COBOL

In order to use some REST/JSON APIs, we need to be able to process NULL value in COBOL.

We had oppened the TS004435032 support case on this matter.

Is it possible to add cobol support for NULL values or to add it to the JSON PARSE & GENERATE JSON statements, as you did with booleans ?

As a suggestion, a NULL could also be generated automatically in the GENERATE statement if the cobol variable only contains LOW-VALUE.

    An other way to manage NULL value would be to declare a condition-name (88 level) of « NULL » associated to the data-item to nullify

    01 top-level.
    05 a-proterty-nullable PIC X.
    88 NULL value space.
    05 another-property-nullable PIC S9(10).
    88 NULL value -1.

    NULL is a reserved name. Can be « isnull » or « When-null »...

    On parse :
    - When property is null, assign value defined by level 88 to data-item, equivalent of « set NULL of a-property-nullable to true »

    On generate :
    - When value of data-item is equal to level 88, write « ”a-property-nullable”: null »

    This avoue to deal with low-value in numeric data-item (wich can use value zero as null value) .
