Calculate length of a string.
Source position: line 0
function Length( |
S: AStringType |
):Integer; |
A: DynArrayType |
):Integer; |
Length returns the length of the string S, which is limited to 255 for shortstrings. If the strings S is empty, 0 is returned.
Note: The length of the string S is stored in S[0] for shortstrings only. The Length fuction should always be used on ansistrings and widestrings.
For dynamical arrays, the function returns the number of elements in the array.
None.
