Depurar un programa en Basic
Puntos de quebra e execución paso a paso
Para verificar erros en cada liña do programa en Basic pode usar a execución paso a paso. É fácil rastrexar erros xa que ve inmediatamente o resultado de cada paso. No editor, un apuntador na columna de punto de quebra indica a liña actual. Tamén pode estabelecer un punto de quebra para forzar a interrupción do programa nunha determinada posición.
Double-click in the breakpoint column at the left of the Editor window to toggle a breakpoint at the corresponding line. When the program reaches a breakpoint, the program execution is interrupted.
The single step execution using the Single Step icon causes the program to branch into procedures and functions.
The procedure step execution using the Procedure Step icon causes the program to skip over procedures and functions as a single step.
Propiedades dun punto de quebra
Para ver as propiedades dun punto de quebra dispoñíbeis no menú de contexto, prema co botón dereito do rato no punto de quebra na columna correspondente.
You can activate and deactivate a breakpoint by selecting Active from its context menu. When a breakpoint is deactivated, it does not interrupt the program execution.
Select Properties from the context menu of a breakpoint or select Breakpoints from the context menu of the breakpoint column to call the Breakpoints dialog where you can specify other breakpoint options.
The list displays all breakpoints with the corresponding line number in the source code. You can activate or deactivate a selected breakpoint by checking or clearing the Active box.
The Pass Count specifies the number of times the breakpoint can be passed over before the program is interrupted. If you enter 0 (default setting) the program is always interrupted as soon as a breakpoint is encountered.
Prema Eliminar para retirar o punto de quebra do programa.
Observación do valor de variábeis
You can monitor the values of a variable by adding it to the Watch window. To add a variable to the list of watched variables, type the variable name in the Watch text box and press Enter.
Os valores de variábeis só se mostran se fan parte do ámbito. As variábeifile:///home/vanessavilaverde/OpenOffice.org3.zips non definidas na localización do código fonte actual mostran ("Out of Scope" - «fóra de ámbito») en vez dun valor.
É posíbel incluír matrices na xanela Monitorización. Se introduce o nome dunha variábel de matriz sen un valor de índice na caixa de texto Monitorización, móstrase o contido da matriz completa.
Se deixa o rato sobre unha variábel predefinida no editor en tempo de execución, móstrase o contido da variábel nunha caixa emerxente.
Xanela Chamadas a pila
Provides an overview of the call hierarchy of procedures and functions. You can determine which procedures and functions called which other procedures and functions at the current point in the source code.
