+ Notes on the MS-DOS Perl port

+ Diomidis Spinellis
+ (dds@cc.ic.ac.uk)
+
+[0. First copy the files in the msdos directory into the parent
+directory--law]
+
+1. Compiling.
+
+ Perl has been compiled under MS-DOS using the Microsoft
+C compiler version 5.1. Before compiling install dir.h as
+<sys/dir.h>. You will need a Unix-like make program (e.g.
+pdmake) and something like yacc (e.g. bison). You could get
+away by running yacc and dry running make on a Unix host,
+but I haven't tried it. Compilation takes 12 minutes on a
+20MHz 386 machine (together with formating the manual), so
+you will probably need something to do in the meantime. The
+executable is 272k and the top level directory needs 1M for
+sources and about the same ammount for the object code and
+the executables.
+
+ The makefile will compile glob for you which you will
+need to place somewhere in your path so that perl globbing
+will work correctly. I have not tried all the tests or the
+examples, nor the awk and sed to Perl translators. You are
+on your own with them. In the eg directory I have included
+an example program that uses ioctl to display the charac-
+teristics of the storage devices of the system.
+
+2. Using MS-DOS Perl
+
+ The MS-DOS version of perl has most of the functional-
+ity of the Unix version. Functions that can not be provided
+under MS-DOS like sockets, password and host database
+access, fork and wait have been ommited and will terminate
+with a fatal error. Care has been taken to implement the
+rest. In particular directory access, redirection (includ-
+ing pipes, but excluding the pipe function), system, ioctl
+and sleep have been provided.
+
+2.1. Interface to the MS-DOS ioctl system call.
+
+ The function code of the ioctl function (the second
+argument) is encoded as follows:
+
+- The lowest nibble of the function code goes to AL.
+- The two middle nibbles go to CL.
+- The high nibble goes to CH.
+
+ The return code is -1 in the case of an error and if
+successful:
+
+- for functions AL = 00, 09, 0a the value of the register DX
+- for functions AL = 02 - 08, 0e the value of the register AX
+- for functions AL = 01, 0b - 0f the number 0.
+
+ See the perl manual for instruction on how to distin-
+guish between the return value and the success of ioctl.
+
+ Some ioctl functions need a number as the first argu-
+ment. Provided that no other files have been opened the
+number can be obtained if ioctl is called with
+@fdnum[number] as the first argument after executing the
+following code:
+
+ @fdnum = ("STDIN", "STDOUT", "STDERR");
+ $maxdrives = 15;
+ for ($i = 3; $i < $maxdrives; $i++) {
+ open("FD$i", "nul");
+ @fdnum[$i - 1] = "FD$i";
+ }
+
+2.2. Binary file access
+
+ Files are opened in text mode by default. This means
+that CR LF pairs are translated to LF. If binary access is
+needed the `binary' function should be used. There is
+currently no way to reverse the effect of the binary func-
+tion. If that is needed close and reopen the file.
+
+2.3. Interpreter startup.
+
+ The effect of the Unix #!/bin/perl interpreter startup
+can be obtained under MS-DOS by giving the script a .bat
+extension and using the following lines on its begining:
+
+ @REM=("
+ @perl %0.bat %1 %2 %3 %4 %5 %6 %7 %8 %9
+ @end ") if 0 ;
+
+(Note that you will probably want an absolute path name in
+front of %0.bat).

The autodecrement is not magical.

+The range operator (in an array context) makes use of the magical
+autoincrement algorithm if the minimum and maximum are strings.
+You can say
+
+ @alphabet = (\'A\' .. \'Z\');
+
+to get all the letters of the alphabet, or

+ $hexdigit = (0 .. 9, \'a\' .. \'f\')[$num & 15];
+
+to get a hexadecimal digit, or
+
+ @z2 = (\'01\' .. \'31\'); print @z2[$mday];
+
+to get dates with leading zeros.
+(If the final value specified is not in the sequence that the magical increment
+would produce, the sequence goes until the next value would be longer than
+the final value specified.)
