Created page with "<pre> BinaryMid( <binary-array>, <start>, <length> ) </pre> === Description === Create a binary variable by extracting a number of bytes from another binary variable. === Par..."

New page

<pre>
BinaryMid( <binary-array>, <start>, <length> )
</pre>

=== Description ===

Create a binary variable by extracting a number of bytes from another binary variable.

=== Parameters ===

==== binary-array ====

The binary variable to use.

==== start ====

Optional; Position to start from.

Default is 0;

==== length ====

Optional; How many bytes to copy.

Default is all remaining bytes;

=== Return Value ===

Success: Returns a new binary variable.

Failure: Returns 0.

=== Remarks ===

This does not modify the original.

=== Example ===

Copy from "brown" to end of the data:

<syntaxhighlight lang="sputnik">
$binary = Pack("z0", "The quick brown FoX")
$binary2 = BinaryMid($binary, 10)
println("b1: " . Unpack("z0", $binary))
println("b2: " . Unpack("z0", $binary2))
</syntaxhighlight>

Copy just the "FoX" part example:

<syntaxhighlight lang="sputnik">
$binary = Pack("z0", "The quick brown FoX")
$binary2 = BinaryMid($binary, 16, 3)
println("b1: " . Unpack("z0", $binary))
println("b2: " . Unpack("z0", $binary2))
</syntaxhighlight>
