====== 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|
|varSize|An optional parameter.  This should be set the byte size of the data to be returned.  This argument is only required if varType is CHAR or BINARY.||

 
==== Returns ====
 
A binary value based on the offset, type and size.

==== Example ====
 
<code>
/* 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 )
