CHARACTER declaration
  • CHARACTER S*10, T="len4", U*20/"initialization"/
ALIAS named substrings
ALIAS(T,3, tt,2) tt == T
= set a string
S = "some text" some te
() single character index
S = T(2) e
>< SWAP (sub-)strings
S >< U values e
: FromTo
S = S(10:1) txet em
// join untrimmed
S = "A  " // "BC" A  BC
& Join trimmed
S = "A  " & "BC" ABC
&& join, 1 space
S = "A  " && "BC" A BC
&&& join, 2 spaces (etc)

$ linear index of left-hand side string

$1 inlineLoop index
S = &("+-") +-+-+-+-
CHAR number to character
CHAR(65) "A"
ICHAR character to number

EDIT(Text=U, Right="i", RePLace=".", DO) .n.t.al
InlineLoop indexed string loop
maximum = MAX( A( $1, $1) ) 9
