I haven't used CXML but I have done a lot of FORTRAN. As far as I understand it, language specific runtime libraries including the FORTRAN one come with the base operating system and do not normally show up separately in $ PRODUCT SHOW PRODUCT. In VAX days, the relevant file was SYS$SHARE:FORRTL.EXE.? On Alpha, it looks likely to be SYS$SHARE:DEC$FORRTL.EXE, however, it may not be quite that simple as there are also other translated images present which may be accessed using a logical name - $ SHOW LOGICICAL *FORRTL* Try writing a Hello World FORTRAN program.? If that runs ok, your FORTRAN runtime library is at least present and you probably need to concentrate on finding a newer version. If you have the extended message help installed, $ HELP /MESSAGE may give you some helpful hints about whatever error message you are getting. Regards, Peter Coghlan.

There should have been a SYS$SHARE:DEC$FORRTL.EXE present from when the operating system was installed but installing the FORTRAN compiler may have updated it. This is a missing source include file and is not related to the run time library.? It is needed at compile time, not at run time.? I suspect it is normally found in what VMS calls a text library file, probably matching SYS$SHARE:*DEF.TLB - include files used by the FORTRAN compiler are to be found in SYS$SHARE:FORSYSDEF.TLB for example.? (These are binary files - you can use LIBRARY /LIST to list their contents or LIBRARY /EXTRACT to examine a particular member.) On the other hand, there may not be a text library file involved and CXML may be expecting to find a plain text file called CXMLDEF.FOR - it might be worth looking for this in and around SYS$EXAMPLES: When a relatively new compiler is installed on an older operating system (V7.2-1 in this case), it is sometimes necessary to update the run time library in order to take advantage of some of the new features provided by the compiler. I can't recall if this has to be done separately or if it happens automatically (if appropriate) when the compiler is installed.? I think the latter. A newer run time library than the one that comes with VMS 8.4 may not be available. If you installed FORTRAN first and then CXML, it may be worth trying the other way around in case CXML is getting confused by an updated run time library provided by the FORTRAN install.? Unfortunately, I can't see an easy way to get back where you started from except by starting with a fresh install of the operating system. Anyway, if the CXML install allowed you to continue even though it complained about the run time library, I think there will be few consequences.? I imagine things will just work once you solve the missing include file problem. Regards, Peter Coghlan.
