dosWriteReg(string Key, string SubKey, string ValueName, any Value)

Writes a value into the registry. If needed, sub keys that do not exist will be created. If the value doesn't exist within the key, it will be created, otherwise it will be overwritten. 

Parameters :

Key : A string specifying which root key to write in. This parameter is case insensitive. All possible values are "HKEY_CURRENT_USER", "HKEY_CURRENT_CONFIG", "HKEY_USERS", "HKEY_LOCAL_MACHINE" and "HKEY_CLASSES_ROOT". 
SubKey : A string specifying which subkey to write the value in. This may include nested subkeys separated by backslashes. For example "Software\Control Panel\Desktop". This parameter is case insensitive and may be an empty string to specify the root key specified by Key
ValueName : A string specifying which value to write within a key. For example "IconTitleFaceName". This parameter is case insensitive and may be an empty string to specify the default value in the key.
Value : Data to write to the value. The type of this parameter will specify which type of value to write. This may be a null terminated string for a string, an integer for a dword value or a linear list of linear lists of integers for a binary value. In a binary value, each index of the linear list passed is a linear list representing a byte. Each index of each linear list within the passed linear list is an integer representing a bit. If an integer is not 0, the corresponding bit is on. If an integer is 0, the corresponding bit is off. For example the binary sequence 10001010 01010101 can be passed as [[1, 0, 0, 0, 1, 0, 1, 0], [0, 1, 0, 1, 0, 1, 0, 1]]. 

Return Value : An integer indicating whether the value was successfully written. If 1 is returned, the method was successful. If 0 is returned, the method was not successful is which case dosGetLastError() should be called to determine the cause of the error. 

Possible Returned Error Codes via dosGetLastError() :
10001 : Invalid value for parameter 1. 
10004 : Invalid format for parameter 4. A value type other than a string, integer or linear list was passed. If a linear list was passed, a value within it is not a linear list of 8 elements containing all integers. 
10022 : Method is not supported on MacOS. 
11000 : Registry value not found. Can not create a key in the specified location.
