Closing 2 files +in io.c was not good enough. I am trying again with closing 4 files. +Still failed. I am going to have to add some diagnostics to identify +the failure. + +And the beginfile1 test also is failing on VMS 8.3 Alpha. I will look +at that after I resolve the manyfile issue. + +I also did not notice that ofmta test failed on VMS 7.3 VAX. The +floating point number is rounding differently. I get the same result +with the replacement SNPRINTF or the VMS provided SNPRINTF. + +TOAD> diff ofmta.ok sys$disk:[]_ofmta.tmp +************ +File SRC_ROOT:[GAWK.TEST]OFMTA.OK;1 + 5 4.234 + 6 4.2345 hi +****** +File LCL_ROOT:[GAWK.TEST]_OFMTA.TMP;2 + 5 4.235 + 6 4.2345 hi +************ + +I tried that build again with #undef HAVE_VPRINTF, and it failed. + + From eval.c: + I1 8733 #ifndef HAVE_VPRINTF + I1 8734 #error "you lose: you need a system with vfprintf" + .1 +%CC-E-ERRORMESSAGE, (1) #error "you lose: you need a system with vfprintf" + +Note that the error message has the wrong routine name. + +I have looked over the manual, and will try to get some detailed changes +to it. + +Some preliminary things to help collect my thoughts. + +As the MMS program has a lot of issues with ODS-5, Some open source +programmers have switched to Madgoat Make, known as MMK from +https://github.com/endlesssoftware/mmk . MMK uses most unmodified MMS +description files and handles ODS-5 volumes better than MMS does. + +The optional POSIX subsystem is no longer supported on VMS. While I +used to know at what version this support stopped in my head, I have +forgotten, and so far have not found that with an online search. + +Most of the C runtime routines that formerly required the POSIX +subsystem are in the VMS C runtime, so there no separate POSIX builds +needed for newer versions of VMS. + +The behavior of the VMS C runtime is controlled by feature settings that +can be set by logical names before the program is run. + +These feature settings include the support of longer filenames with +almost any characters including UTF-8, on ODS-5 volumes and if routines +should behave in a more Unix like fashion. + +I will be adding vms_crtl_init.c to the next commit for vmsbuild.com and +descrip.mms. This vms_crtl_init.c detects when the program is running +under a bash or similar shell and sets the feature settings for better +UNIX compatibility, or sets them for better DCL compatibilities. +It makes sure that the extended filename support is enabled. +This way a single binary can be used for both the VMS environment and +the DCL environment. + +As a replacement, a GNV https://sourceforge.net/projects/gnv/ was +created. There is older version of gawk that is provided by that package. + +Recently a group of programmers have started trying to correct issues +with the GNV project and reorganize it as a collection of packages along +wth a VMSPORTS https://sourceforge.net/projects/vms-ports/ effort. + +The GNV environment provides a Bash shell and several other utilities +intended to simulate a Unix environment. + +The web page https://sourceforge.net/p/gnv/wiki/InstallingGNVPackages/ +documents what needs to be done before installing these newer packages +while GNV is in the transition phase. + +Currently only Bash 4.2.45 and Coreutils 8.21 have been packaged, both +are fixing critical issues in GNV. + +I plan to have a GAWK PCSI package that will be installed with the VMS +PRODUCT command. This package will install into the GNV directory +structure, which mimics a Linux directory tree, so I will need to +determine where to put the gawk.hlp file in it. + +Regards, +-John + + + +On 12/6/2013 7:20 PM, John E.
