⎕A - Return Latin Alphabet

Z←⎕A returns the 26-character uppercase Latin alphabet.
Z is the character vector 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'.

The name is case sensitive, so ⎕A is different from ⎕a which returns 'abcdefghijklmnopqrstuvwxyz'. There are also ten other variations on this system function each of which returns either the lower- or upper-case accented alphabet as in ⎕á ⎕Á ⎕à ⎕À ⎕â ⎕Â ⎕ä ⎕Ä ⎕ã ⎕Ã. For example:

      ⍪⎕a ⎕á ⎕à ⎕â ⎕ä ⎕ã 
 abcdefghijklmnopqrstuvwxyz  
 ábćdéfǵhíjḱĺḿńóṕqŕśtúvẃxýź 
 àbcdèfghìjklmǹòpqrstùvẁxỳz 
 âbĉdêfĝĥîĵklmnôpqrstuvwxyz 
 äbcdëfgḧïjklmnöpqrsẗüvẅẍÿz 
 ãbcdẽfghĩjklmñõpqrstũṽwxỹz 
      ⍪⎕A ⎕Á ⎕À ⎕Â ⎕Ä ⎕Ã 
 ABCDEFGHIJKLMNOPQRSTUVWXYZ 
 ÁBĆDÉFǴHÍJḰĹḾŃÓṔQŔŚTÚVẂXÝŹ 
 ÀBCDÈFGHÌJKLMǸÒPQRSTÙVẀXỲZ

 ÄBCDËFGḦÏJKLMNÖPQRSTÜVẄẌŸZ 
 ÃBCDẼFGHĨJKLMÑÕPQRSTŨṼWXỸZ  

The result of ⎕A may be used as any other string, including referencing individual letters. For example:

      ⎕A[8 5 12 12 15] 
HELLO
