Documentation: help string variables

[Lutz M. <lut...@gm...>]

When I type “help string” in gnuplot 5.2.2 I get the message

Ambiguous request 'string'; possible matches:
	string variables
	stringcolumn
	strings

However, the section “string variables” seems inaccessible; as “help string variables” just returns the same message, and “help strings” doesn’t seem to have a subsection “variables”.

Best,

Lutz
