 * before the function returns.

 *

 * and there is no way to "examine" the item on the floor, while the

 * use of "capital" letters will "examine" an inventory/equipment item,

 * and prompt for its use.

 *

 * directly (0 to 35), and return TRUE.

 *

 * If a legal item is selected from the floor, we save it in "cp" as

 * a negative (-1 to -511), and return TRUE.

 *

 * warning message, using "str" if available, and return FALSE.

 *

 * If no item is selected, we do nothing to "cp", and return FALSE.

 *

 * Global "p_ptr->command_new" is used when viewing the inventory or equipment

 * to allow the user to enter a command while viewing those screens, and

 * also to induce "auto-enter" of stores, and other such stuff.

 *

 * Global "p_ptr->command_wrk" is used to choose between equip/inven/floor

 * listings.  It is equal to USE_INVEN or USE_EQUIP or USE_FLOOR, except

 * when this function is first called, when it is equal to zero, which will

 * cause it to be set to USE_INVEN.

 *

 * We always erase the prompt when we are done, leaving a blank line,

 * or a warning message, if appropriate, if no items are available.
