Option: include

-include=path

Specifies a directory to be searched for files specified by INCLUDE statements. Unlike other command-line options, this setting is cumulative; that is, if it is given more than once on the command line, all the directories so specified are placed on a list that will be searched in the same order as they are given. The order in which ftnchek searches for a file to be included is: the current directory; the directory specified by environment variable FTNCHEK_INCLUDE if any; the directories specified by any -include options; the directory specified by environment variable INCLUDE ; and finally in a standard system-wide directory (/usr/include for UNIX, SYS$LIBRARY for VMS, and \include for MSDOS).
