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.”
