Most strange. Try this: MODCB ACB=acb,DDNAME=(*,0(R3))
The macro is using "I don't know what it's called", as documented here: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/DGT2D570/1.2.1 <quote> An expression of the form (*,scon), where scon is an expression valid for an S-type address constant, including the base-displacement form. The address specified by scon is indirect, that is, it is the address of an area that contains the value of the keyword. The contents of the base register are added to the displacement to determine the address of the fullword of storage that contains the value of the keyword. If an indirect S-type address constant is used, the value it points to must meet the following criteria: If it is a numeric quantity or an address, it must occupy a fullword of storage. If it is an alphanumeric character string, it must occupy two words of storage, be left aligned, and be filled on the right with blanks. </quote> -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
