Usage notes

If the JAR element is packaged inline, it must immediately follow the ++JAR MCS and must not contain any records starting with ++. Neither FROMDS, nor RELFILE, nor TXLIB can be specified on the ++JAR MCS when the element is packaged inline.
To be packaged inline, a JAR file element must contain fixed-block-80 records. To achieve this, the original element can be extracted from a UNIX file system into a data set (using the TSO command OGET for example), and then GIMDTS can be used to transform the element into fixed-block-80 records.
