Support for COBOL data description entries
In the COBOL data description entries specified in a copybook, Z Data Tools supports:
- ASSIGN clause
- OCCURS clause (including OCCURS DEPENDING ON)
- PICTURE clause
- REDEFINES clause
- RENAMES clause
- USAGE clause
- VALUE clause
Z Data Tools ignores:
- BLANK WHEN ZERO clause
- DATE FORMAT clause
- EXTERNAL clause
- GLOBAL clause
- JUSTIFIED clause
Note: In general, Z Data Tools treats Numeric Edited fields as alphanumeric.
A special code, ZA, is used for unsupported zoned decimals.
Z Data Tools supports all data item level numbers except 88 (condition-names).
The literal value that you specify in a VALUE clause is used in the template to specify the Start value (for numeric fields) or Pattern (for alphanumeric fields) “create attribute” on the Field Attributes panel for that field.
Z Data Tools uses this attribute to initialize the value of the field when creating data or inserting new fields when copying data.
