This information is intended to help customers write VTAM® application programs that use VTAM's logical unit (LU) 6.2 support.
This document is for system programmers who code VTAM application programs that use VTAM's LU 6.2 support. This audience can include programmers who are modifying existing programs or writing new ones. The information can also be of use to planners who are estimating the amount of work required to use the VTAM interface.
You should be familiar with LU 6.2 architecture before you write LU 6.2 programs. The SNA Transaction Programmer's Reference Manual for LU Type 6.2 provides this familiarity and is, therefore, a core requisite for using this document.
