The F$PARSE() lexical can be used to verify a file specification or to extract portions of a valid file specification.

The “parse_type” keywords are SYNTAX_ONLY and NO_CONCEAL.

SYNTAX_ONLY parses a file spec and returns values whether the specified file exists or not.

NO_CONCEAL can be used to get the translation of a logical defined with the CONCEALED translation attribute.
