pce->for_name_reference

pce ->for_name_reference: message=code

Executes code for each defined global name reference (e.g. @pce, @arg1). The exit status of the code is ignored. Arguments:

@arg1	Name of the global object (e.g. `pce`, `arg1`).

This method passes the reference-names rather than the objects themselves. As various of them are functions, good understanding of the expansion-rules for functions is necessary.
