It consists of a list, possibly empty, each of whose elements specifies one argument. Each argument specifier is also a list with either one or two fields. If there is only a single field in the specifier then it is the name of a required argument; if there are two fields, then the first is the name of an optional argument and the second is its default value. Required arguments may only be in the beginning and in the end of the argument list, surrounding any optional arguments. .PP There is one special case to permit procedures with variable numbers of arguments. If one formal argument has the name .QW \fBargs\fR , then a call to the procedure may contain more actual arguments than the procedure has formal arguments. In this case, all of the actual arguments starting at the one that would be assigned to \fBargs\fR are combined into a list (as if the \fBlist\fR command had been used); this combined value is assigned to the local variable \fBargs\fR. .PP When \fIname\fR is invoked a local variable will be created for each of the formal arguments to the procedure; its value will be the value of corresponding argument in the invoking command or the argument's default value. .PP Arguments with default values need not be specified in a procedure invocation. However, there must be enough actual arguments for all the formal arguments that do not have defaults, and there must not be any extra actual arguments unless \fBargs\fR is present. .PP Actual arguments are assigned to formal arguments in the following order. .IP Required arguments to the left are assigned from left-to-right. .IP Required arguments to the right are assigned from right-to-left. .IP Optional arguments to the left of any "\fBargs\fR" are assigned from left-to-right. .IP Optional arguments to the right of any "\fBargs\fR" are assigned from right-to-left. .IP Any remaining arguments are assigned to "\fBargs\fR" if it exists, or it is an error to have remaining arguments. .PP When \fIbody\fR is being executed, variable names normally refer to local variables, which are created automatically when referenced and deleted when the procedure returns. One local variable is automatically created for each of the procedure's arguments. Other variables can only be accessed by invoking one of the \fBglobal\fR, \fBvariable\fR, \fBupvar\fR or \fBnamespace upvar\fR commands. The current namespace when \fIbody\fR is executed will be the |
