GetBinaryValue Function
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, BINARY | |

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 )
