"Aardvark") ("VicugnaPacos" . "Alpaca") ("MyrmecophagaTridactyla" . "Anteater"))) ;; So I evaluate it, and it is there: ;; andromeda-assoc-table-1 ⇒ (("OrycteropusAfer" . "Aardvark") ("VicugnaPacos" . "Alpaca") ("MyrmecophagaTridactyla" . "Anteater")) (defconst andromeda-assoc-table-2 '(("Dasypodidae" . "Armadillo") ("TaxideaTaxus" . "Badger") ("Beaver" . "Beaver"))) ;; andromeda-assoc-table-2 ⇒ (("Dasypodidae" . "Armadillo") ("TaxideaTaxus" . "Badger") ("Beaver" . "Beaver")) (defconst andromeda-assoc-table-3 '(("LynxRufus" . "Bobcat") ("LepomisMacrochirus" . "Bluegill") ("RangiferTarandus" . "Caribou"))) ;; andromeda-assoc-table-3 ⇒ (("LynxRufus" . "Bobcat") ("LepomisMacrochirus" . "Bluegill") ("RangiferTarandus" . "Caribou")) (defun my-assoc-lists () (let* ((name "andromeda-assoc-table-") (list '()) (counter 1)) (while (boundp (intern (concat name (number-to-string counter)))) (setq list (append list (symbol-value (intern (concat name (number-to-string counter)))))) (setq counter (1+ counter))) list)) Then you evaluate this function: ;; (my-assoc-lists) ⇒ (("OrycteropusAfer" . "Aardvark") ("VicugnaPacos" . "Alpaca") ("MyrmecophagaTridactyla" . "Anteater") ("Dasypodidae" . "Armadillo") ("TaxideaTaxus" . "Badger") ("Beaver" . "Beaver") ("LynxRufus" . "Bobcat") ("LepomisMacrochirus" . "Bluegill") ("RangiferTarandus" . "Caribou")) That way you can add any number instead of XX `andromeda-assoc-table-XX' and function will add them all together. You need not update your other function with new symbols such as `andromeda-assoc-table-23' or number of them. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
