VBScript Functions

Note

The behavior of VBScript functions such as MidB, ChrB, LeftB, and AscB depends on the byte ordering of the hardware platform, and the number of bytes used to represent Unicode characters in the system software. The functions will produce different results on different operating systems. The behavior described in this section pertains to the Win32 version.
