How the Environment Determines Which Statements Are Permitted

The environment where you are using SQL determines the kinds of SQL statements you can invoke:

• Native TSO sessions or TSO running under ISPF cannot invoke SQL statements that perform cursor operations. Cursor operations deal directly with REXX and CLIST variables. Therefore, the CA OPS/MVS product does not allow you to invoke cursor operation statements from a TSO terminal.
• TSO/E REXX programs, TSO CLISTs, and OPS/REXX programs (including AOF rules) can invoke all of the SQL statements CA OPS/MVS supports, including statements that do cursor operations.
