$mid is a string manipulation identifier used to return a sub-string portion of a string.

Contents

Synopsis

  • $mid( ,S [, N ] )

Parameters

  • text String from which to return a portion
  • S Position within Text. If S is negative, position is relative to the end of Text instead of the beginning. Using Zero behaves same as position 1.
  • N Optional Length. If Length parameter not used, returns entire remainder of the string. If N is zero, returns the numeric length of the string. If N is negative, returns the string beginning at position S except for the LAST $Abs(N) characters.

Properties

None

Examples

//echo -a $mid(abcdefghij,2,3)
returns 3 characters beginning at position 2
//echo -a $mid(abcdefghij,2)
//echo -a $mid(abcdefghij,2,9999)
both return ALL characters beginning at position 2. Omitting N avoids the need to use N as a too-large number like 9999
//echo -a $mid(abcdefghij,-6,2)
returns 2 characters beginning at position 6th from the end. Is equivalent to:
//echo -a $left($right(abcdefghij,6) ,2)
//echo -a $mid(abcdefghij,-6)
returns ALL characters beginning at position 6th from the end.
//echo -a $mid(abcdefghij,3,-2)
returns ALL characters beginning at position 3 EXCEPT for the last 2 characters.
//echo -a $mid(abcdefghij,3,0)
returns the length of the string beginning at position 3.
