Performance

Unless you specify the EXTDSPOPT(*NODFRWRT) parameter (no deferred writing) in the CRTCBLMOD or CRTBNDCBL command, the ILE COBOL compiler buffers all extended DISPLAY statements until the next ACCEPT statement is encountered. While the *NODFRWRT option allows you to associate data errors with the statements that cause them by performing DISPLAY statements as they are encountered, the deferred writing (*DFRWRT) option improves performance by buffering data streams generated by consecutive DISPLAY statements.
