The dateform mode of the session is INTEGERDATE and column F1 in the table INTDAT is a DATE value with the explicit format ' YYYY,MMM,DD '.

SELECT F1 FROM INTDAT ;

The result (without a type change) is the following report:

F1
----------
1900,Dec,31

Assume that you want to convert this to a value of CHAR(12), and an explicit output format of ' MMMBDD,BYYYY '. Use nested CAST phrases and a FORMAT to obtain the desired result: a report in character format.

SELECT
CAST( (CAST (F1 AS FORMAT 'MMMBDD,BYYYY')) AS CHAR(12))
FROM INTDAT;

The result after the nested CASTs is the following report.

F1
------------
Dec 31, 1900

The inner CAST establishes the display format for the DATE value and the outer CAST indicates the data type of the desired result.
