'Switch' or 'Case' would clean up some real ugly If loops

Jerry Thomas · Post by **Jerry Thomas** » Fri Oct 08, 2010 2:46 pm

I am sure there are lots of these in use:

If>a
Else
If>b
Else
If>c
etc.

Any chance of adding a Switch (or Case) command?

Switch>some_str
SwitchIf>a
(if some_str = a, do this, then skip to EndSwitch)
SwitchIf>b
(if some_str = b, do this, then skip to EndSwitch)
SwitchIf>c
(if some_str = c, do this, then skip to EndSwitch)
EndSwitch

+1 on that.

I'm sure this is something Grovkillen and Jerry already know about, but just in case anyone else is searching the forums for an easy way to make a string entirely upper or lower case, this is how I do it :

Code: Select all

VBSTART
VBEND

let>sampletext=AbcdefGhIJKLmnOPQ

// change all to lower case
VBEval>LCase("%sampletext%"),sampletext
messagemodal>%sampletext%

// change all to upper case
VBEval>UCase("%sampletext%"),sampletext
messagemodal>%sampletext%

There is also this

Code: Select all

let>sampletext=AbcdefGhIJKLmnOPQ

// change all to lower case
UpperCase>sampletext,sampletext
MDL>sampletext

// change all to upper case
LowerCase>sampletext,sampletext
MDL>sampletext

We are mixing Cases here (bad pun intended...)

Parsnipnose3000 and Rain are refering to UPPERCASE and lowercase.

The original bug/request was dealing with the Switch statement that is sometimes called a Case statement

Code: Select all

evaluate (something)
If a
  do this
If b 
  do this
...
else
  do this

Why not do this?

Code: Select all

Label>Start

Let>some_str=a

IF>some_str=a,DoThis,EndSwitch

Label>EndSwitch
  MDL>some_str = False
  //Do Something
Goto>Start

Label>DoThis
  MDL>some_str = True
  //Do Something
Goto>Start

OR

Code: Select all

Let>some_str=a

IF>some_str=a,DoThis,EndSwitch

SRT>EndSwitch
  MDL>some_str = False
END>EndSwitch

SRT>DoThis
  MDL>some_str = True
END>DoThis

Yes, that would work.

But it would be cleaner if we had a real Switch or Case statement!

Besdies, if we don't keep asking for new stuff, what is Marcus going to do in all his free time?

I think this is what I was asking for in THIS enhancement suggestion. Because of the way Macro Scheduler works I don't see any other way to do it. Create an OnEvent function that jumps to a subroutine the moment a variable acquires a particular value. I think that would accomplish this request. Don't know what kind of load multiple OnEvents constantly checking variable values would place on the system.

I agree, it would be very nice. This topic does make me wonder (again) why the If>expression,true_label_name,false_label_name form is deprecated

VBScript has Select Case, maybe that has possibilities?
