$! SET VERIFY
$!
$! For example, if you unpacked perl into: [USER.PERL-5n...] then you will
$! want to cd into the tree and execute Configure:
$!
$! $ SET DEFAULT [USER.PERL5_xxx]
$! $ @Configure
$!
$! or
$!
$! $ SET DEFAULT [USER.PERL5_xxx]
$! $ @Configure "-des"
$!
$! That's it. If you get into a bind trying to build perl on VMS then
$! definitely read through the README.VMS file.
$! Beyond that send email to [email protected]
$!
$! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$!
$! send suggestions to:
$! Dan Sugalski <[email protected]>
$! Thank you!!!!
$!
$! Adapted and converted from Larry Wall & Andy Dougherty's
$! "Configure generated by metaconfig 3.0 PL60." by Peter Prymmer
$! (a Bourne sh[ell] script for configuring the installation of perl
$! on non-VMS systems) in the perl5.002|3 epoch (spring/summer 1996)
$! with much valuable help from Charles Bailey &
$! the whole VMSPerl crew.
$! Extended and messed about with by Dan Sugalski
$!
$! VMS-isms we will need:
$ echo = "write sys$output "
$ cat = "type"

$! max_allowed_dir_depth = 2 ! e.g. [A.PERLxxx] not [A.B.PERLxxx]
$!
$! Sebastian Bazley's request: close the CONFIG handle with /NOLOG
$! qualifier "just in case" (configure.com is re @ed in a bad state).
$! This construct was tested to be not a problem as far back as
$! VMS V5.5-2, hopefully earlier versions are OK as well.
$!
$ CLOSE/NOLOG CONFIG
$!
$! Now keep track of open files
$!
$ vms_filcnt = F$GETJPI ("","FILCNT")
$!
$!: compute my invocation name
$ me = F$ENVIRONMENT("PROCEDURE")
$!
$! Many null statements (begin with colon ':') in the Bourne shell version of
$! this script serve as comments/placeholders. I have retained some of the ones
$! that will help you compare this .COM file to the sh version - as well as
$! leave placeholders for future improvements to this .COM file.
