FreeVirtualVariablesPrefixed

Procedure FreeVirtualVariablesPrefixed(prefix: string)

This function removes all VirtualVariables begining with prefix from memory.

This is useful because you can specify several settings with different prefixes, e.g. win_ for all VirtualVariables to do with setting up the window, which can be freed immediately after, ini_ for initialisation variables that can be freed after the program is done starting up, etc
