High Quality Content by WIKIPEDIA articles! IBM mainframe utility programs are supplied with IBM mainframe operating systems such as MVS to carry out various tasks associated with datasets, etc.Many of these utilities were designed by IBM users, through the group SHARE, and then modified or extended by IBM from versions originally written by a user.IDCAMS ("Access Method Services") generates and modifies VSAM and Non-VSAM datasets. The "Access Method" reference derives from the initial "VSAM replaces all other access methods" mindset of OS/VS. It probably has the most functionality of all the utility programs, performing many functions, for both VSAM and non-VSAM files. It was intended to replace most of the other dataset utility programs.
