Chapter 2 Developing with LF Fortran size is a number greater than 4095 enclosed in parenthesis. It is the minimum variable size in bytes that will be placed on the heap. Variables smaller than size bytes are not placed on the heap. If size is omitted, it defaults to 4096. Use the -varheap option when creating programs that have large local arrays. If you notice that increasing the size of a local array causes a stack overflow, using -varheap may alleviate this condition. Note that the -varheap option does not apply to variables having the SAVE attribute, which includes initialized variables. -VERSION Display Version, Copyright and Registration Information Disables compile and link. Default: none The -version option causes the compiler version, copyright and registration information to be printed. Any other options specified on the command line are ignored. -[N]W Compiler Warnings Compile only. Default: -w Specify -nw to suppress compiler warning and informational messages. -WARN, -FULLWARN Linker Warnings Link only. Default: no warnings The linker detects conditions that can potentially cause run-time problems but are not necessarily errors. LF Fortran supports two warning levels: -warn, and -fullwarn. -warn enables basic linker warning messages. -fullwarn provides the maximum level of warning and informational messages. -[N]WIDE Extend width of fixed source code Compile only. Default: -nwide Using the -wide option causes the compiler to accept fixed form source code out to column 255. The default is to accept code out to column 72 -WIN or -WINCONSOLE Windows Compile and link. Default: -winconsole 46 LF Fortran Express User’s Guide
Compiler and Linker Options Specifying -winconsole will create a console mode application. A Windows console will be created if the program is invoked from Windows Explorer, a menu selection, or a program icon, and it will disappear after program completion unless the -pause option is specified. If the program is invoked from the command line of an existing console, all console I/O will be performed within that console. Specifying -win will create a Windows mode application. Under Windows 9x, console I/O is not permitted if the -win option was specified. Console I/O with -win is allowed if your program is running under a newer Windows operating system. If your program reads from or writes to standard output, a console will be created and will disappear upon program completion. See also -[N]PAUSE -[N]WO Warn Obsolescent Compile only. Default: -nwo Specify -wo to generate warning messages when the compiler encounters obsolescent Fortran 95 features. -[N]XREF [(f=fval[,i=ival])] Cross-Reference Listing Compile only. Default: -nxref Specify -xref to generate cross-reference information. This information is shown in the listing file in addition to the information that the -lst option would provide. Note that -xref overrides -lst. By default, cross reference file names consist of the root of the source file name plus the extension .lst. You may optionally specify f for the listing file name, or i to list the contents of INCLUDE files. fval specifies the listing file name to use instead of the default. If a file with this name already exists, it is overwritten. If the file can't be overwritten, the compiler aborts. If the user specifies a listing file name and more than one source file (possibly using wild cards) then the driver diagnoses the error and aborts. ival is one of the characters of the set [YyNn], where Y and y indicate that include files should be included in the listing and N and n indicate that they should not. By default, include files are not included in the listing. Example LF95 myprog -xref(i=y) creates the cross reference file myprog.lst and outputs cross reference information for the source file.
