Local routines inside procedures

I would very much like to have the possibility to add local routines inside procedures/functions (like in Clarion CPD). This would save many gotos and/or separate small procedures, which make the code harder to read and maintain.

Hi Ola,

I would this also very appriciate !

I am just wondering, why can't they do this. I wouldn't think it is too difficult?!?!?

best regards

Just in case PCS does not understand what I am talking about here, I am referring to a command which is known as "gosub" in Basic and "do" in Clarion...:-)

Even the simpliest home computers had a gosub command already in the 80's...

Ola,

You have GOTO in WinDev.

...code here

GOTO Label


:Label
...code here

Hi Carlo,

I am aware of the Goto command. I try to avoid it, but use it when necessary. But it is not the same as calling a local routine, which in many languages is done with gosub. Goto continues the code from where it ends, while gosub would return to where it was called from.

Routines can be built using Goto, but the code will be rather awkward, even ugly:

Some code here
CallingPoint = "A"
Goto Subroutine1
ReturnPointA:
And the code continues...

Return //This procedure ends here

Subroutine1:
Do some deed
Switch CallingPoint
  CASE "A": Goto ReturnpointA
  CASE "B": Goto ReturnpointB
END

------------------

There are some workarounds:

Instead of a procedure, create a window, and then you can use the window's local procedures. This is a good, or even a better solution especially when the procedure actually needs a window to ask for parameters and to show progress.

Use global procedures like local routines. This I don't like; it is like shooting a fly with an 88 mm FlaK. If the local subroutine is needed only in its parent process, then putting it in a global procedure unnecessarily breaks the compactness of the code and makes it more difficult to re-use the main process in other programs.

WD's windows have local procedures, so I really wonder why procedures (and Reports!!!) cannot have local routines in a similar way?

Local routines would help make the main code more manageable, readable and maintainable. It could then be divided into logical parts. Routine would also help avoid repeating some pieces of code. Especially it would help break down some long IF and SWITCH structures.

Every self-respecting programming language has a gosub command (or equivalent). Unfortunately Wlanguage does not.

Hello Ola,

Maybe I do not understand but would CALL or EXECUTE work for this?

It seems that PCSoft is finally introducing this feature in Wx20.
