I want to write a REXX tool to open the PDS and then this locate this member, take the current date as input from the USER. Here, the existing date should go to the previous date(whatsoever is the current date currently should be shifted to previous date), current date should be the date taken from USER as input and next date should be the current date+1(always). '**' will be the difference between prev date & current date, next '**' will be the diff between current date & next date and the last date will again be the current date. So, the PDS name can be taken as the input from the USER and after taking it, the program should locate the member name, open the member and make these changes. Is it possible to so this with REXX?
