chars()
Syntax
chars(
stringExpression
,
firstCharacter
,
lastCharacter
)
Description
Function; identifies a substring of characters in stringExpression
. The substring starts at firstCharacter
and ends at lastCharacter
. The expressions firstCharacter
and lastCharacter
must specify a position in the string.
If firstCharacter
and lastCharacter
are equal, then a single character is returned from the string. If lastCharacter
is greater than the string length, only a substring up to the length of the string is identified. If lastCharacter
is before firstCharacter
, the function returns the value EMPTY
.

Example
This statement identifies the sixth through tenth characters of the word Macromedia:
put chars("Macromedia", 6, 10) -- "media"
