Syntax

Based on the action specified, you may require one or more additional parameters

HKEY is the "Hive Key" where the key is to be placed. These hives are files that are loaded by your machine when booting and compose the registry structure. By default, most scripts use HKLM as the work hive. Valid HKEY values are:

• HKLM
• HKCU
• HKCR
• HKEY_USERS
• HKEY_CURRENT_CONFIG

Section is the complete path to the section where the key is to be read from. Note: The Section (i.e path to the Key) specified here MUST exist or an error will occur. ¹

Key is the name of the 'child key' in that section to be read. Note: The KEY specified here MUST exist or an error will occur. ¹

• APPEND - Writes a string at the end of the specified key.

RegMulti,<HKEY>,<Section>,<Key>,APPEND,<String>

• PREPEND - Writes a string at the start of the specified key.

RegMulti,<HKEY>,<Section>,<Key>,PREPEND,<String>

• BEHIND - Writes a string after the matchings sub-string.

RegMulti,<HKEY>,<Section>,<Key>,BEHIND,<SubString>,<String>

• PLACE - Writes a string at the specified index. If the string already exists in the current value, a warning is written and the current value is left unchanged.

RegMulti,<HKEY>,<Section>,<Key>,PLACE,<Index>,<String>
