Now that is something absolutely fundamental I didn't know.
Thanks Marcus.

From the AUG (Advanced Users Guide) for the RCL command:

Quote:RCL searches the entire current path, starting with the current directory. To search a different path, specify { path name }, where path is the new path to the variable name. The path subdirectory does not become the current subdirectory (unlike EVAL).

Though it's not stated explicitly, this same behavior is applied to many built-in operations where an implicit RCL of a variable is executed. I can't remember the details at the moment, but I'm pretty sure there are at least a couple exceptions to this rule. It all boils down to which SysRPL opcode is used to get a variable's contents onto the stack. Most of the time the parent directories are searched.

Note that this isn't the same as searching all directories. Just the ones in the current path are included.
