Description
Returns the value of a variable at a given offset.
Syntax
val = GetBinaryValue(variable, offset, varType [, varSize]
Parameters
The function has the following parameters:
| Parameter | Description |
|---|---|
| variable | A binary structure to return data from. |
| offset | The starting offset of the data to be extracted |
| varType | The type of data within the variable, i.e., CHAR, INT |
| varSize | An optional parameter. This should be set the byte size of the data to be returned. |
Returns
A binary value based on the offset, type and size.

Example
/* This example takes the following steps: 1. Converts an ANSI string to UNICODE 2. Determines the length of the string 3. Extracts the first 10 characters from the string 4. Converts the UNICODE string to ANSI */ ansi_string = "Hello World" * Convert the string to Unicode unicode_string = ANSI_Unicode( ansi_string : \00\ ) uniLength = GetByteSize( unicode_string ) val = GetBinaryValue( unicode_string, 1, CHAR, 10 ) newString = Unicode_ANSI( val )
