VSAM file access

VSAM (Virtual Storage Access Method) is a specialized form of disk file storage that is supported on AIX® and on IBM® mainframes that run z/OS® or VSE.
When you are writing code in EGL and intend to access a VSAM file, create a Record part that is based on one of the following stereotypes:
IndexedRecord
To access a VSAM Key Sequenced Data Set (KSDS).
RelativeRecord
To access a VSAM Relative Record Data Set (RRDS).
SerialRecord
To access a VSAM Entry Sequence Data Set (ESDS).

The resource association file types that provide VSAM access are vsam, vsamrs, and ibmcobol, as described in “Resource association part.”
