+.SH DESCRIPTION
+.PP
+Tcl allows a number of mathematical functions to be used in
+expressions, such as \fBsin\fR, \fBcos\fR, and \fBhypot\fR.
+These functions are represented by commands in the namespace,
+\fBtcl::mathfunc\fR.  The \fBTcl_CreateMathFunc\fR function is
+an obsolete way for applications to add additional functions
+to those already provided by Tcl or to replace existing functions.
+It should not be used by new applications, which should create
+math functions using \fBTcl_CreateObjCommand\fR to create a command
+in the \fBtcl::mathfunc\fR namespace.
+.PP
+In the \fBTcl_CreateMathFunc\fR interface,
+\fIName\fR is the name of the function as it will appear in expressions.
+If \fIname\fR does not already exist in the \fB::tcl::mathfunc\fR
+namespace, then a new command is created in that namespace.
+If \fIname\fR does exist, then the existing function is replaced.
+\fINumArgs\fR and \fIargTypes\fR describe the arguments to the function.
+Each entry in the \fIargTypes\fR array must be
+one of \fBTCL_INT\fR, \fBTCL_DOUBLE\fR, \fBTCL_WIDE_INT\fR,
+or \fBTCL_EITHER\fR to indicate whether the corresponding argument must be an
+integer, a double-precision floating value, a wide (64-bit) integer,
+or any, respectively.
+.PP
+Whenever the function is invoked in an expression Tcl will invoke
+\fIproc\fR.  \fIProc\fR should have arguments and result that match
+the type \fBTcl_MathProc\fR:
+.PP
+.CS
+typedef int \fBTcl_MathProc\fR(
+        ClientData \fIclientData\fR,
+        Tcl_Interp *\fIinterp\fR,
+        Tcl_Value *\fIargs\fR,
+        Tcl_Value *\fIresultPtr\fR);
+.CE
+.PP
+When \fIproc\fR is invoked the \fIclientData\fR and \fIinterp\fR
+arguments will be the same as those passed to \fBTcl_CreateMathFunc\fR.
+\fIArgs\fR will point to an array of \fInumArgs\fR Tcl_Value structures,
+which describe the actual arguments to the function:
+.PP
+.CS
+typedef struct Tcl_Value {
+    Tcl_ValueType \fItype\fR;
+    long \fIintValue\fR;
+    double \fIdoubleValue\fR;
+    Tcl_WideInt \fIwideValue\fR;
+} \fBTcl_Value\fR;
+.CE
+.PP
+The \fItype\fR field indicates the type of the argument and is
+one of \fBTCL_INT\fR, \fBTCL_DOUBLE\fR or \fBTCL_WIDE_INT\fR.
+It will match the \fIargTypes\fR value specified for the function unless
+the \fIargTypes\fR value was \fBTCL_EITHER\fR. Tcl converts
+the argument supplied in the expression to the type requested in
+\fIargTypes\fR, if that is necessary.
+Depending on the value of the \fItype\fR field, the \fIintValue\fR,
+\fIdoubleValue\fR or \fIwideValue\fR
+field will contain the actual value of the argument.
+.PP
+\fIProc\fR should compute its result and store it either as an integer
+in \fIresultPtr->intValue\fR or as a floating value in
+\fIresultPtr->doubleValue\fR.
+It should set also \fIresultPtr->type\fR to one of
+\fBTCL_INT\fR, \fBTCL_DOUBLE\fR or \fBTCL_WIDE_INT\fR
+to indicate which value was set.
+Under normal circumstances \fIproc\fR should return \fBTCL_OK\fR.
+If an error occurs while executing the function, \fIproc\fR should
+return \fBTCL_ERROR\fR and leave an error message in the interpreter's result.
+.PP
+\fBTcl_GetMathFuncInfo\fR retrieves the values associated with
+function \fIname\fR that were passed to a preceding
+\fBTcl_CreateMathFunc\fR call.  Normally, the return code is
+\fBTCL_OK\fR but if the named function does not exist, \fBTCL_ERROR\fR
+is returned and an error message is placed in the interpreter's
+result.
+.PP
+If an error did not occur, the array reference placed in the variable
+pointed to by \fIargTypesPtr\fR is newly allocated, and should be
+released by passing it to \fBTcl_Free\fR.  Some functions (the
+standard set implemented in the core, and those defined by placing
+commands in the \fBtcl::mathfunc\fR namespace) do not have
+argument type information; attempting to retrieve values for
+them causes a NULL to be stored in the variable pointed to by
+\fIprocPtr\fR and the variable pointed to by \fIclientDataPtr\fR
+will not be modified.  The variable pointed to by \fInumArgsPointer\fR
+will contain -1, and no argument types will be stored in the variable
+pointed to by \fIargTypesPointer\fR.
+.PP
+\fBTcl_ListMathFuncs\fR returns a Tcl value containing a list of all
+the math functions defined in the interpreter whose name matches
+\fIpattern\fR.  The returned value has a reference count of zero.

+be invoked, depending on whether the target interpreter is safe

-.PP
-This procedure may be invoked to announce that a package has been
-linked statically with a Tcl application and, optionally, that it
-has already been loaded into an interpreter.
-Once \fBTcl_StaticPackage\fR has been invoked for a package, it
-may be loaded into interpreters using the \fBload\fR command.
-\fBTcl_StaticPackage\fR is normally invoked only by the \fBTcl_AppInit\fR
-procedure for the application, not by packages for themselves
-(\fBTcl_StaticPackage\fR should only be invoked for statically
-loaded packages, and code in the package itself should not need
-to know whether the package is dynamically or statically loaded).
-.PP
-When the \fBload\fR command is used later to load the package into
-an interpreter, one of \fIinitProc\fR and \fIsafeInitProc\fR will
-be invoked, depending on whether the target interpreter is safe
-or not.
-\fIinitProc\fR and \fIsafeInitProc\fR must both match the
-following prototype:
-.PP
-.CS
-typedef int \fBTcl_PackageInitProc\fR(
-        Tcl_Interp *\fIinterp\fR);
-.CE
-.PP
-The \fIinterp\fR argument identifies the interpreter in which the package
-is to be loaded.  The initialization procedure must return \fBTCL_OK\fR or
-\fBTCL_ERROR\fR to indicate whether or not it completed successfully; in
-the event of an error it should set the interpreter's result to point to an
-error message.  The result or error from the initialization procedure will
-be returned as the result of the \fBload\fR command that caused the
-initialization procedure to be invoked.
-.PP
-\fBTcl_StaticPackage\fR can not be safely used by stub-enabled extensions,
-so its symbol is not included in the stub table.

+.SH DESCRIPTION
+.PP
+\fINote: the \fBcase\fI command is obsolete and is supported only
+for backward compatibility.  At some point in the future it may be
+removed entirely.  You should use the \fBswitch\fI command instead.\fR
+.PP
+The \fBcase\fR command matches \fIstring\fR against each of
+the \fIpatList\fR arguments in order.
+Each \fIpatList\fR argument is a list of one or
+more patterns.  If any of these patterns matches \fIstring\fR then
+\fBcase\fR evaluates the following \fIbody\fR argument
+by passing it recursively to the Tcl interpreter and returns the result
+of that evaluation.
+Each \fIpatList\fR argument consists of a single
+pattern or list of patterns.  Each pattern may contain any of the wild-cards
+described under \fBstring match\fR.  If a \fIpatList\fR
+argument is \fBdefault\fR, the corresponding body will be evaluated
+if no \fIpatList\fR matches \fIstring\fR.  If no \fIpatList\fR argument
+matches \fIstring\fR and no default is given, then the \fBcase\fR
+command returns an empty string.
+.PP
+Two syntaxes are provided for the \fIpatList\fR and \fIbody\fR arguments.
+The first uses a separate argument for each of the patterns and commands;
+this form is convenient if substitutions are desired on some of the
+patterns or commands.
+The second form places all of the patterns and commands together into
+a single argument; the argument must have proper list structure, with
+the elements of the list being the patterns and commands.
+The second form makes it easy to construct multi-line case commands,
+since the braces around the whole list make it unnecessary to include a
+backslash at the end of each line.
+Since the \fIpatList\fR arguments are in braces in the second form,
+no command or variable substitutions are performed on them;  this makes
+the behavior of the second form different than the first form in some
+cases.
