Coding Tip: Using data sessions

[barrymavin]

You can save and restore data sessions like this.

SAVE DATASESSION TO m_session
// do something opening up new tables
RESTORE DATASESSION FROM m_session

When using .rsp web pages you can maintain the exact state (database, tables, and record etc) of each cursor between pages like this.

// On entry to the .rsp page.

IF type( '_session["state"]' ) != "U"
     m_state = _session["state"]
     RESTORE DATASESSION FROM m_state
ELSE
     // open up your tables for the first time
ENDIF

// On exit of the .rsp page.
SAVE DATASESSION TO m_state
_SESSION["state"] = m_state

Notice how you can store any variables into the _session[] dynamic array.
