Data structure subfields start with the DCL-SUBF keyword, but the keyword is optional unless the name is the same as a free-form operation code (op code). Example 13 illustrates a subfield declaration where the DCL-SUBF keyword is required. The DCL-SUBF keyword must be used because read is an op code supported in free-form.

Example 13. Data structure with the DCL-SUBF keyword

DCL-DS record_one;
buffer CHAR(25);
DCL-SUBF read INT(3);
END-DS;
