Format
copytext(T,Start=1,End=0)
Returns
A text string.
Args
T
: A text string.Start
: The text byte position in which to begin the copy.End
: The text byte position immediately following the last character to be copied.
Copy characters in T between Start and End. The default end position of 0 stands for length(T)+1
, so by default the entire text string is copied.
pre = copytext("Hi there",1,3))// = "Hi"
post = copytext("Hi there",4)) // = "there"
If the start or end position is negative, it counts backwards from the end of the string.
post = copytext("Hi there",-5)) // = "there"
Note
In strings containing non-ASCII characters, byte position and character position are not the same thing. Use
copytext_char()
to work with character counts instead of bytes, at a performance cost. See the Unicode section for more information.
