Description
is the name of the file to include.
HP Fortran statements
INCLUDE
The keyword INCLUDE and character-literal-constant form an INCLUDE line, which is
used to insert text into a program prior to compilation. The inserted text replaces the INCLUDE
line; the INCLUDE line should therefore appear in your program where you want the inserted
text. When the end of an included file is reached, the compiler continues processing with the
line following the INCLUDE line.
character-literal-constant can be either a file name or a device name. It must not have a
kind parameter that is a named constant.
The INCLUDE line must appear on one line with no other text except possibly a trailing
comment. It should not have a statement label. Thus, you cannot branch to it, and it cannot be
an action statement that is part of a Fortran 90 IF statement. You cannot use the “;” operator
to add a second INCLUDE line, nor can you use the “&” operator to continue it over another line.
The compiler searches directories for the named include files in the following order:
1. The current source directory
2. Directories specified by the -I compile-line option, in the order specified
3. The current working directory
4. The directory /usr/include
INCLUDE lines can be nested to a maximum of ten levels. However, they must be nested
nonrecursively. That is, inserted text must not specify an INCLUDE line that was encountered
at an earlier level of nesting.
Line numbering within the listing of an included file begins at 1. When the included file
listing ends, the include level decreases appropriately, and the previous line numbering
resumes.
