Are you talking about a DCB only or a DCB with an accompanying DCBE ?? If the second, I don't agree. Thanks to some enlightenment from Mr Rutledge, all my Assembler programs run AMODE(31), RMODE(ANY). 1). GETMAIN storage location as ANY. 2). Copy DCB to GETMAINed area 3). Open file as example: OPEN (FILE,(INPUT)),MODE=31 4). Get File as example: GET FILE,AREA 5). Close file as example: CLOSE (FILE),MODE=31 This just a simple example of input file process. FILE points to GETMAINed area and all DCB's have their own accompanying DCBE. At no time is execution changed from 31-bit to 24-bit or back again. Don't understand what you are saying about OPEN parameterlist being below the line. Mine aren't and it works perfectly. I don't see any reason why all Assembler programs can't run 31-bit.
