You should try to determine what the executable file format is. If SCO or Unixware modules will not run, then you are restricted to whatever source will compile with your existing compiler.
By your description, the OS sounds like an early version of Unixware (before Novell purchased it.) I attached a simple C program that converts lower case to uppercase.

Hi all,
I've got a question about an OS upgrade.
I'm planning to do a upgrade from AIX UNIX 4.3.2 to 4.3.3 in a few weeks.
I haven't got that much information.
Could someone give me some general tips or hints, things I should think of before? Things I should know, or general errors.

Hello. I have inherited a HP 9000 series E35 server that has stopped working. It is running HPUX (10.2-I think). The fault light is on (steady) on the front of the server and it will not boot. It only goes to a CM> prompt, which I have never seen before. Initial research through HP indicated a... (8 Replies)

Questions:
Why would we want to upgrade? Benefits?
Do we need to install v2 and then v3 or can we just go straight to v3?
I see we can get the following:

Hello to all UNIX experts! This is my problem: I have to emulate an old UNIX System 5 release 4 on a virtual machine. I've got 30 images (.IMA) of 1.4M floppy where there is the installation of SVR4.

tolower_l
TOUPPER(3) Linux Programmer's Manual TOUPPER(3)NAME
toupper, tolower - convert letter to upper or lower case
SYNOPSIS
#include <ctype.h>
int toupper(int c);
int tolower(int c);
DESCRIPTION
toupper() converts the letter c to upper case, if possible.
tolower() converts the letter c to lower case, if possible.
If c is not an unsigned char value, or EOF, the behavior of these functions is undefined.
RETURN VALUE
The value returned is that of the converted letter, or c if the conversion was not possible.
CONFORMING TO
C89, C99, 4.3BSD.
BUGS
The details of what constitutes an uppercase or lowercase letter depend on the current locale. For example, the default "C" locale does
not know about umlauts, so no conversion is done for them.
In some non-English locales, there are lowercase letters with no corresponding uppercase equivalent; the German sharp s is one example.
