Of course users in the z/OS are working exclusively whit encoded EBCDIC. But the new program does not support the encoding EBCDIC. But in new programs need is there on z/OS. Therefore, the use of ASCII support on z/OS makes it easy to running new programs with minimal modifications, you need only include the ASCII support system in the program. Of course users on z/OS you want to control and set the tag for all files using chtag. But the more programs will use the ASCII support the less you need to install the tag in the manual mode using chtag. When using programs with ASCII support so it tag will be set automatically . Users need only turn on ASCII support system by setting environment variable (_BPXK_AUTOCVT=ON) in USS z/OS. > > Remember, we don't exclusively work in OMVS.
