2304 @code{clear} is called with at least one argument, only the visible\n\ | |
2305 names matching the arguments are cleared. For example, suppose you have\n\ | |
2306 defined a function @code{foo}, and then hidden it by performing the\n\ | |
2307 assignment @code{foo = 2}. Executing the command @kbd{clear foo} once\n\ | |
2308 will clear the variable definition and restore the definition of\n\ | |
2309 @code{foo} as a function. Executing @kbd{clear foo} a second time will\n\ | |
2310 clear the function definition.\n\ | |
