I asume you are fresh from a windows C environment jumped into the linux world. You need to read that message carefully again. Rob is almost right with his statement. First you need to know in the windows world the differences between W98, XP and Vista. when you write a program for one of those versions it does not work out the box in one of the other 3. uuuuhmmm yes I know it can work sometimes but there is no garanty. I wrote a programm with the WMP SDK71 on W98 and that does not work on the others. Simple because MS changed something in the background for XP, Vista not tried. This was using a binary package installer as you prefer. The source can also be compiled for XP and Vista. I do have 3 packages and 3 times the size to use for the simple 1 file installer for the same program. If we do the same for "linux" programs you must understand there are over 100 different distributions, name them w98,w98se,me,xp,vista,2000,nt. Yes some are constructed from a master like Debian is used for the ubuntu series. Mandriva for i.e. PCLinux2007, RedHat for fedora, Centos, etc. In MS Window terms the Home, Premium, Ultimate etc. Let say we support ten of those master systems, we need ten times the size of our full program. Your mentioned 35MB was for ONE distribution, so we need 350MB now, half a CD. (the source is less then 20MB ATM usable for all ten systems and children of them) Now comes the support to get a working system. We need the 4 most used Database engines. Some PDF, XML and network support as i.e. Curl. Everey one of the 10 master distributions compiles these on there likes for ordering in the disk map, the configuration and possible options. Just a number but let say for a system you need 50MB to support this in compiled form. Now the 10 master distributions need 10 times 50MB as 500MB (almost a full CD) (the source is less then 50MB and usable for all ten systems and children of them) These support may already be installed by the distribution or are available for installation as binary packages, and full supported for bug fixes by them. If the guy that makes a program like gambas should do the way you want he must deliver a file with a size for all code: 35MB gambas compiled x 10 = 350MB 50MB support compiled x 10 = 500MB some setup program and total 850MB at least. Give HIS support on the supporting code DB,PDF,XML and network stuff. Noway he will or can do this. Do you release your program with this as requirement? He wil never have enough time to live anymore or to make his application (gambas). Second: this file will be picked up by major sites as Download.com and snapfiles and many insecure sites( for dismanteling and add malware/virus and repacked) for the simple windows to linux jumpers that doeds want the "easy way without thinking". Third: When I want to jump to an other linux distribution it is simple a few commands to make a working version again. For my WMP application, having the source you can change the function name changed between W98 and XP and recompile to get it working again. Binary delivery is only usefull if it is done for a specific distribution by that distribution or the programmer head/leader. This is a safe place to get the program and for new people starting with linux the distributions repository is the onle safe place anyway. For programmers it should not be a problem to compile a fresh new release of the developer program used for creating there own programs, they need to compile there own programs to. (not every program language has a IDE to do it) Do not see the figures and conditions as absolute but as indication what is involved in the total process to do a job as you prefer (or did after read this). It shows why source delivery and prefers this way in the linux world. I do also follow your thread about the C/C++ based character input. You can be a good programmer for applications now in C/C++ but do not understand the working and background of C/C++, only your programs. Porting a C program source to Basic source is not simple copy/past the code and in the editor using the replace function to change the C statements text to Basic words. You need to understand what the specific C statement does and find the Basic statement to do the same thing. The grammar/syntax between both languages are also different. > PUBLIC SUB Main() > > ' Declare AND initialize variables. > DIM count AS Integer > ' The values are initialized at Zero, by above command Wrong. In C, int Count; The value is not set to zero here in Basic (for gambas). The name is specified and a memory location is reserved for storage of the value with the name 'count' If you ask in VB it will tell you the value is 'Nothing' or 'Null' In C/C++ it works the same, it declares a name and memory location. For gambas it does or should do the same, but if you do count = count +1 and may by the variable handler seen the value is not set (Null) and preset to 0 (zero) for the expresion evaluator and result is then 1. In PHP program language it also say Null and the increment results to 1. > > DIM c AS String > > ' READ , PRINT , AND count characters. > PRINT "Enter characters (Ctrl+D to quit): " > LINE INPUT c > PRINT c The (LINE) INPUT (and PRINT) are line oriented text statements. the getchar in C is a character based statement, it wait for key press and returns The INPUT waits for the CR charactercode 13 dec. or 0D hex. and returns the buffer filled with pressed keys. For the print you will see the line behaviour by the way the single letters are every time on a new line. > count += Len(c) You asume here len(c) = 0 or 1. Wrong it is 0, 1, 2 or even more. C is variable type of string and that can hold 0 to 10000 characters. The type of Byte or Char should be the more correct one. > WHILE NOT Eof ' This doesnt works No wonder. Eof what? As mentioned in a previous post the Eof function belongs to the stream object. Gambas Wiki says:http://gambasdoc.org/help/lang/eof?view Result = Eof ( [ Stream AS Stream ] ) AS Boolean' Returns TRUE if we are at the end of the stream. If Stream is not specified, then the standard input is used so While Eof() should be the correct line. See LINE INPUT for an example:http://gambasdoc.org/help/lang/lineinput?view > 'PRINT c1 > LINE INPUT c > count += Len(c) > PRINT c > WEND Why len(c), You want/are working with single character input. Just 'INC count' or 'count += 1' is enough. :) > > ' PRINT the number OF characters printed. > PRINT count & " characters printed." > >END Stream & Input/Output functions:http://gambasdoc.org/help/cat/stream?view READ:http://gambasdoc.org/help/lang/read?view READ [ # Stream , ] Variable [ , Length ] LINE INPUT c should be READ c,1 or READ c WRITE:http://gambasdoc.org/help/lang/write?view WRITE [ # Stream , ] Expression [ , Length ] PRINT c should be WRITE c,1 or WRITE c These two are the best to simulate the char i/o in C/C++ Try next PUBLIC SUB Main() ' Declare AND initialize variables.

PRINT "Enter characters (or Press Carriage Return to quit): " READ cha,1 WHILE (cha <> KEY.Return) WRITE cha,1 count += 1 READ cha 'get next character WEND WRITE cha ' PRINT the number OF characters printed. PRINT count & " characters printed."
