HEIRARCHY
The descendants of EL_BENCHMARK_COMPARISON below were created to benchmark particular code characteristics. Any of the benchmarks can be run from a menu shell.
The class DEVELOPER_COMPARISON is used to create throw-away benchmarks that answer particular questions. After benchmarking new code, it is discarded but the results are documented in the section "Benchmark Journal" below.

EL_BORROWED_STRING_32_CURSOR
Cursor to use an across loop as an artificial scope in which a temporary STRING_32 buffer can be borrowed from a shared pool. After iterating just once the scope finishes and the buffer item is automatically returned to the shared pool stack.

EL_BORROWED_STRING_8_CURSOR
Cursor to use an across loop as an artificial scope in which a temporary STRING_8 buffer can be borrowed from a shared pool. After iterating just once the scope finishes and the buffer item is automatically returned to the shared pool stack.
Further Information

EL_BORROWED_STRING_CURSOR
Cursor to use an across loop as an artificial scope in which a temporary string buffer conforming to STRING_GENERAL can be borrowed from a shared pool. After iterating just once the scope finishes and the buffer item is automatically returned to the shared pool stack.
Further Information
Click on class link to see notes.
EL_BORROWED_STRING_SCOPE
Defines an across loop scope in which a string conforming to STRING_GENERAL can be borrowed from a factory pool and then automatically returned after the first and only iteration of the cursor.
EL_BORROWED_ZSTRING_CURSOR
Cursor to use an across loop as an artificial scope in which a temporary ZSTRING buffer can be borrowed from a shared pool. After iterating just once the scope finishes and the buffer item is automatically returned to the shared pool stack.

EL_STRING_POOL
Map character capacities to reuseable buffer strings. A negative count indicates that the string item is "on loan" as a buffer. A positive count indicates the string is available to borrow.
The borrowed_item routine returns the best match for a preferred capacity.
EL_STRING_POOL_SCOPE
Defines an across loop scope in which multiple strings can be borrowed from a shared pool and automatically returned when the loop exits after first and only iteration
EL_STRING_POOL_SCOPE_CURSOR
Artificial scope defined by an across loop in which strings can be borrowed from a pool See class EL_STRING_POOL_SCOPE
