## Registry Commands


The subkey and the value name are given together in a single parameter, separated by a backslash; the part after the last backslash is the value name.

**registry.set** <root>, <subkey\name>, <type>, <value> - Writes a value to the registry. <type> is REG_DWORD for an integer, otherwise a string is written.

**registry.get** <root>, <subkey\name>, <accumulator> - Reads a value from the registry into the accumulator (empty if the value does not exist).


Example:

**registry.set** HKCU, Software\MyApp\Build, REG_DWORD, 42

**registry.get** HKCU, Software\MyApp\Build, _build
