// Global ACS strings (Formerly known as On the fly strings)

// This special string table is part of the global state. Programmatically
// generated strings (e.g. those returned by strparam) are stored here.
// PCD_TAGSTRING also now stores strings in this table instead of simply
// tagging strings with their library ID.
//
// Identical strings map to identical string identifiers.
//
// When the string table needs to grow to hold more strings, a garbage
// collection is first attempted to see if more room can be made to store
// strings without growing. A string is considered in use if any value
// in any of these variable blocks contains a valid ID in the global string
// table:
// * The active area of the ACS stack
// * All running scripts' local variables
// * All map variables
// * All world variables
// * All global variables
// It's not important whether or not they are really used as strings, only
// that they might be. A string is also considered in use if its lock count
// is non-zero, even if none of the above variable blocks referenced it.
//
// To keep track of local and map variables for nonresident maps in a hub,
// when a map's state is archived, all strings found in its local and map
// variables are locked. When a map is revisited in a hub, all strings found
// in its local and map variables are unlocked. Locking and unlocking are
// cumulative operations.
//
// What this all means is that:
// * Strings returned by strparam last indefinitely. No longer do they
// disappear at the end of the tic they were generated.
// * You can pass library strings around freely without having to worry
// about always having the same libraries loaded in the same order on
// every map that needs to use those strings.
