{{task}} [[Category:String manipulation]] {{omit from|Lilypond}}
A pangram is a sentence that contains all the letters of the English alphabet at least once.
For example: ''The quick brown fox jumps over the lazy dog''.
;Task: Write a function or method to check a sentence to see if it is a [[wp:Pangram|pangram]] (or not) and show its use.

AppleScript
Out of the box, AppleScript lacks many library basics – no regex, no higher order functions, not even string functions for mapping to upper or lower case.
From OSX 10.10 onwards, we can, however, use ObjC functions from AppleScript by importing the Foundation framework. We do this below to get a toLowerCase() function. If we also add generic filter and map functions, we can write and test a simple isPangram() function as follows:
use framework "Foundation" -- ( for case conversion function ) -- PANGRAM CHECK ------------------------------------------------------------- -- isPangram :: String -> Bool on isPangram(s) script charUnUsed property lowerCaseString : my toLower(s) on |λ|(c) lowerCaseString does not contain c end |λ| end script length of filter(charUnUsed, "abcdefghijklmnopqrstuvwxyz") = 0 end isPangram -- TEST ---------------------------------------------------------------------- on run map(isPangram, {¬ "is this a pangram", ¬ "The quick brown fox jumps over the lazy dog"}) --> {false, true} end run -- GENERIC FUNCTIONS --------------------------------------------------------- -- filter :: (a -> Bool) -> [a] -> [a] on filter(f, xs) tell mReturn(f) set lst to {} set lng to length of xs repeat with i from 1 to lng set v to item i of xs if |λ|(v, i, xs) then set end of lst to v end repeat return lst end tell end filter -- map :: (a -> b) -> [a] -> [b] on map(f, xs) tell mReturn(f) set lng to length of xs set lst to {} repeat with i from 1 to lng set end of lst to |λ|(item i of xs, i, xs) end repeat return lst end tell end map -- Lift 2nd class handler function into 1st class script wrapper -- mReturn :: Handler -> Script on mReturn(f) if class of f is script then f else script property |λ| : f end script end if end mReturn -- toLower :: String -> String on toLower(str) set ca to current application ((ca's NSString's stringWithString:(str))'s ¬ lowercaseStringWithLocale:(ca's NSLocale's currentLocale())) as text end toLower

In [http://wiki.formulae.org/Pangram_checker this] page you can see the solution of this task.
Fōrmulæ programs are not textual, visualization/edition of programs is done showing/manipulating structures but not text ([http://wiki.formulae.org/Editing_F%C5%8Drmul%C3%A6_expressions more info]). Moreover, there can be multiple visual representations of the same program. Even though it is possible to have textual representation —i.e. XML, JSON— they are intended for transportation effects more than visualization and edition.
The option to show Fōrmulæ programs and their results is showing images. Unfortunately images cannot be uploaded in Rosetta Code.

## VBA
The function pangram() in the VBScript section below will do just fine.
Here is an alternative version:
```vb
Function pangram2(s As String) As Boolean
Const sKey As String = "abcdefghijklmnopqrstuvwxyz"
Dim sLow As String
Dim i As Integer
sLow = LCase(s)
For i = 1 To 26
If InStr(sLow, Mid(sKey, i, 1)) = 0 Then
pangram2 = False
Exit Function
End If
Next
pangram2 = True
End Function
```
Invocation e.g. (typed in the Immediate window):
```txt
print pangram2("the quick brown dog jumps over a lazy fox")
print pangram2("it is time to say goodbye!")
```
