<ANSI string>.CharactTypeCount (Function)
Returns the number of characters matching a given type.
WordCount (Function)
Returns the number of words in a string.
LineToPosition (Function)
Returns the position of the first character of a line in a block of text.
StringReverse (Function)
Reverses the characters of a string.
ASCIIZ string of (Variable type)
The ASCIIZ string of type is used to manipulate strings with a null character at the end, denoted by a zero (as in the C programming language).
<ANSI string>.Insert (Function)
Inserts a string into another character string at a given position.

Length (Function)
Returns:
  • the length of a string, i.e., the number of characters in the string (including spaces and binary zeros).
  • the size of a buffer, i.e., the number of bytes in the buffer.
ExtractLine (Function)

String of (Variable type)
The String of type is used to manipulate fixed-length strings. These strings have a null character at the end, denoted by a zero (as in the C programming language).
Unicode string on (Variable type)

<ANSI string>.Increment (Function)
Increments a number at the beginning or at the end of a string.
