Goto::nolabel
The label specified in Goto does not match the label specified in the Label:
Block[{k},
k = 1;
Label["top"];
Print["k = ", k++];
If[k < 4, Goto["Top"]];
"done"
]This shows a valid use of Goto and Label:
Block[{k},
k = 1;
Label["top"];
Print["k = ", k++];
If[k < 4, Goto["top"]];
"done"
