Hello everyone.
I'm developing a (new) iTunes script and I've hit a wall. I'll try to explain my problem:
I would like to be able to select/input cover size for an iTunes source script. So far I've been able to 'cheat' a value in the "CurrentUrl" output, as
Total output:
output["CurrentUrl"]= [https://itunes.apple.com/lookup?media=music&entity=song&limit=200&country=jp&width=1200&id=505371XXX](https://itunes.apple.com/lookup?media=music&entity=song&limit=200&country=jp&width=1200&id=505371XXX) where **&width=1200** is the value I want.
This would be "easily" achieved if there was a way to 'splice' an output S into the current buffer, as in (example):
Script-Line : xx
Command : splice
Parameter 1 : Output "CurrentUrl" (or another)
Output : \>\<
Line and position:
results
.... ^
would return
Line and position:
res**[itunes.apple.com/lookup?media=music&entity=song&limit=200&country=jp&width=1200&id=50537145](http://itunes.apple.com/lookup?media=music&entity=song&limit=200&country=jp&width=1200&id=50537145)**ults
or some command akin to `Replace` where the second parameter would be an output. Then with further processing I could get the "1200" value to the artwork url.
PS: I know about 'Adjust cover' that would achieve the same purpose for this example, but a 'Splice' command could have other uses regarding WS scripting.
Thank you.

With version 3.22 and the addition of a configuration schema, the previous suggestion becomes (more) viable.
Instead of 'cheating' a value in `CurrentUrl`, I'm revising the suggested 'splice' command into a `SayVar "key"` command, with the idea of user inputs from the dedicated Settings menu item being called directly in the script.
Example:
Currently, adding an input box in the settings file, like
```auto
"type": "number",
"key": "testNumber",
"title": "Enter cover size",
"description": "Enter a number",
"default": 42
```
and calling it in the script, using `IfVar`
```auto
IfVar "testNumber" "42"
...
replace "600x600bb" "42x42bb"
EndIf
```
is working. This example allows to define a cover size in the settings menu, and get the cover art in that size; but only if the input is "42".
For this example to work with any input number, it would imply coding `IfVar` clauses for every numeric value, which is impractical. Instead, with a dedicated command, the value would be called directly into the current buffer, like
```auto
...
replace "600x600bb" ""
SayVar "testNumber"
Say "x"
SayVar "testNumber"
Say "bb"
...
```
which would return the same results as before (42x42bb), but would also allow for any numeric/string value to be used.
Another example would be to get the current values on the settings schema in an output, like
```auto
OutputTo "CurrentSettings"
Say "testChoices:"
SayVar "testChoices"
Say "|"
Say "testEnter:"
SayVar "testEnter"
Say "|"
Say "testNumber:"
SayVar "testNumber"
Say "|"
Say "testCheck:"
SayVar "testCheck"
Say "|"
...
```
which would be useful, for example, in debugging.
This is merely a (revised) suggestion for consideration. Feedback would be appreciated.

I also want something like `SayVar "variable"`. And in the `[IndexUrl]`/`[AlbumUrl]` and `[SearchBy]` the possibility to use `$var(variable)`.

I would like to be able to do that too, but from my current understanding of the WS framework structure, I don't think that will be a possibility (for now / if ever). And since it's already possible to call settings' %variables% from a script with `IfVar` in `[ParserScriptIndex]` and `[ParserScriptAlbum]`, I'd like to believe that the groundwork for a possible `SayVar` is already laid out, and this suggestion isn't too far-fetched.

I've had a breakthrough regarding this topic, and managed to call a number input from 'Settings' and import it into an %output% in an efficient manner. For anyone interested, please check

Since this method can work with any number, and I was unable to find any topic (other than my [own](https://community.mp3tag.de/t/suggestion-splice-command-for-ws/61854)) regarding this subject, I've created this topic to explain how I did it, so other authors can benefit from it.
