Missing FORRTL

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.
