Description
Function enable.
When EN = TRUE, generate portion of a string.
When EN = FALSE, no generate operation.
Any non-empty string.
Number of characters to be extracted cannot be greater than the length
of the IN string.
Position of the sub-string. The sub-string first character will be the one
pointed to by Pos (first valid position is 1).
Middle part of the string (its length = NbC).
When the number of characters to extract exceeds the length of the IN
string, NbC is automatically recalculated to get the remainder of the
string only. When NbC or Pos are zero or negative numbers, an empty
string is returned.
Enable out.
