Hello -.A curiosity question about IHAETD macro of SYS1.MACLIB. . ETDHFLAG DS B All non-used bits must be zero. @ ETDRCRD EQU X'80' If bit is ON, NO recording of cross @ * memory connections will be performed. * If bit is OFF, recording will be done. * Classification: DMTI . There is a field ETDHFLAG with an equate ETDRCRD in IHAETD. The comment states: if the bit is ON, no recording of cross memory connections will be performed - . How is this bit set OFF/ON ? When is this bit set OFF/ON ? What determines when this bit is turned OFF/ON ? Where is the data written to/stored? What information is collected ? Can an authorized user program set this Flag before the ETCRE macro is issued ? . Is there any additional documentation on this field other than the macro itself ? . Curious minds want to know.paul..
