If you are using code page IBM-037 in MVS™ and the shell is using code page IBM-1047, you need to convert from one code page to another when:

• Transferring files between a workstation and the file system.
• Copying data between MVS data sets and the file system.
• Passing JCL pathname data to z/OS UNIX programs—unless you restrict yourself to characters in the POSIX portable file name character set.
• Passing JCL parameters and pathnames to a shell invoked from a batch program—unless you restrict yourself to characters in the POSIX portable file name character set.
• Converting between ASCII and EBCDIC when using the pax utility.
