Requirement for an absolute path name

In some situations, an absolute path name is required. Table 1 shows that job control language (JCL) and some TSO/E commands require an absolute path name and that they require an MVS™ data set name to be specified in a certain way. In these situations, the maximum length of the absolute path name is 255 characters.
