====== Restart STORE-VALUE ====== ====Data Arguments Required==== a value to use instead (on an ongoing basis). ====Description==== The **store-value** //[[CL:Glossary:restart]]// is generally used by //[[CL:Glossary:handler|handlers]]// trying to recover from errors of //[[CL:Glossary:type|types]]// such as **[[CL:Types:cell-error]]** or **[[CL:Types:type-error]]**, which may wish to supply a replacement datum to be stored permanently. ====Examples==== <blockquote> ([[CL:Macros:defun]] type-error-auto-coerce (c) ([[CL:Macros:when]] ([[CL:Functions:typep]] c '[[CL:Types:type-error]]) ([[CL:Special Operators:let]] ((r ([[CL:Functions:find-restart]] 'store-value c))) ([[CL:Macros:handler-case]] ([[CL:Special Operators:let]] ((v ([[CL:Functions:coerce]] (type-error-datum c) (type-error-expected-type c)))) ([[CL:Functions:invoke-restart]] r v)) ([[CL:Types:error]] ()))))) <r>TYPE-ERROR-AUTO-COERCE</r> ([[CL:Special Operators:let]] ((x 3)) ([[CL:Macros:handler-bind]] (([[CL:Types:type-error]] #'type-error-auto-coerce)) ([[CL:Macros:check-type]] x [[CL:Types:float]]) x)) <r>3.0</r> </blockquote> ====See Also==== {\secref\Restarts}, {\secref\InterfacesToRestarts}, **[[CL:Functions:invoke-restart|Function INVOKE-RESTART]]**, **[[CL:Functions:store-value|Function STORE-VALUE]]**, **[[CL:Macros:ccase|Macro CCASE]]**, **[[CL:Macros:check-type|Macro CHECK-TYPE]]**, **[[CL:Macros:ctypecase|Macro CTYPECASE]]**, **[[CL:Functions:use-value|Function USE-VALUE]]**, **[[CL:Restarts:use-value|Restart USE-VALUE]]**
