+implicit none forces the types of identifiers to be implicitly undefined.
This is equivalent to specifying IMPLICIT NONE for each program unit
+[no]implicit_none
in each file in the files list. The source code that is to be compiled with
this option may contain other IMPLICIT statements; the statements will
be honored. The default, +noimplicit_none, allows identifiers to be
implicitly defined.
The common blocks listed in file (one per line, no enclosing ‘ / ‘s) are
treated as shared common blocks, but are not attached. The user must
+indirectcommonlist=file
attach or otherwise allocate storage for such common blocks before they
are referenced.
A C language program would typically be used to either attach a shared
memory segment, or malloc a block of memory, and store that address
into the external symbol for the common block. All Fortran code that
references such a common block will indirect through the address in the
external symbol for that indirect common block.
All source files that reference variables in such a common block must be
compiled with the +indirectcommonlist flag, and that common
block name must appear in the named file.
Default initialization of heap variables (mentioned in +initheap_set option)
of type complex. rval is real part and ival is imaginary part of complex
+initheap_complex=rval:ival
number. Valid values for rval and ival are normal real numbers, nan ,
snan.
The numbers represented by rval/ival are mentioned in below table.

snan is supported at default optimization level only.
Default initialization of heap variables (mentioned in +initheap_set option)
of type integer. Valid values of ival are integer values of the form decimal,
octal (starting with 0) and hexadecimal (starting with 0x).

Default initialization of heap variables (mentioned in +initheap_set option)
of type real. Valid values for rval are normal real numbers, nan, snan.

Default Initialization of heap variables is done for the variables specified
by var.
