Hi MajorDill,

Sorry about this. I'm building my website but it will take me longer than expected. See the 1st post.

BASIC Commands
Code:
    rem
    print
    input
    goto
    gosub
    return
    if...then...else
    do...until
    for...to...{step}...next
    while...endw
    on...gosub
    break
    end
    


A set of special console commands is available to make things easier.
These commands return values to reserved variables V0,V1,V2,V3.
See ReadMe.txt for more information.
Code:
    ! Move cursor at position x,y

    x=40
    y=10
    
    color 0,7 : cls
    cursor 1,25
    locate x,y
    inkey
    


Code:
    ! Get mouse information

    do

        mouse

        ! V0 = cell x
        ! V1 = cell y
        ! V2 = button: 1 left, 2 right, 4 double click
        ! V3 = coordinates in pixels (high/low order word)

        title V0,",",V1

        wait 1

    until key(27)<>0

I love this stuff. Excellent materials for beginners to learn from (although there's nothing 'beginners' with the code)

Arrays are 1D and 2D with the pointer starting from 0. Elements of an array are
either signed integer values or strings. The size of an array changes dynamically
by calling DIM again. The initial values of the elements of an array are set to 0.
Code:
    dim a[5]=10,20,30,0x40,50h

    for i=0 to 4
        print "a[",i,"] is ",a[i]
    next
    pause
    


Code:
    dim a[3,3]

    dim b[3,3]=10,20,0x1E,40,50,60,70,80,1011010b

    a[]=b[]   ! copy array

    for y=0 to 2
        for x=0 to 2
        print "a[",x,",",y,"] is ",a[x,y]
        next
    next
    pause
    


Code:
    dim a$[10]="Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct"

    dim a$[12]    ! resize array

    a$[10]="Nov"

    a$[11]="Dec"

    n=size(a$[])  ! get array size

    for i=0 to n-1
        print "a$[",i,"] = ",a$[i]
    next
    pause

It would be very nice if you could share your passion with Tomasz and others at Programming Language & Design section where you can properly introduce your Hobby Basic to the community. Good to see FASM is becoming a language of choice for compiler writing.

^^I feel it's early for that now. The interpreter is far for being complete. Surely i might do that but in later time.


A label is identified by the symbol # at the end of a name. Comments in the
source code start with the symbol ! or the REM command.
Code:
    retry#

    ! line comment
    rem  line comment

    input "Secret number:",n
    if n<>1234 then goto retry
    end
    


Code:
    for x=1 to 3
        on x gosub L1,L2,L3
    next
    pause
    end

    L1# print "Label 1":return
    L2# print "Label 2":return
    L3# print "Label 3":return
    


Anonymous Labels.
Code:
    @@#

    !  @@ followed by # create an anonymous label
    !  goto @b  (backward jump)
    !  goto @f  (forward jump)
    !  Ctrl-C to exit loop

    goto @b

A string variable is identified by the symbol $ at the end of a name.
Concatenation uses the + addition symbol to add parts to a string variable.
Code:
    age=10
    a$="I am "+chr(34)+str(age)+chr(34)+" years old."
    print a$
    pause
    


Code:
    a$="ABCDEFGHIJKLMNOPQRSTUVWXYZ"
    b$=reverse(a$)
    print a$,EOL$,b$
    print left(a$,5)
    pause
    


Code:
    input "How many words:",n
    dim a$[n]

    for i=0 to n-1
        print "Enter word ",i+1,":",
        input a$[i]
    next
    pause
    


Code:
    do
        input "password:",a$
    until comp(trim(a$),"letmein")=1
    print "You are in."
    pause

A set of built-in functions is available. These functions return either an
integer value, or a string pointer. A variable to store the return value
must precede the call.

Code:
    ! abs(n)                    --> int
    ! asc(a$)                   --> int
    ! base(n,radix)             --> string
    ! bin(n)                    --> string
    ! cell(x,y)                 --> int
    ! chr(n)                    --> string
    ! comp(a$,b$)               --> int
    ! find(a$,find$,[start])    --> int
    ! hex(n)                    --> string
    ! key(n)                    --> int
    ! lcase(a$)                 --> string
    ! left(a$,length)           --> string
    ! len(a$)                   --> int
    ! mid(a$,start,length)      --> string
    ! pad(a$,char,length)       --> string
    ! path(n)                   --> string
    ! pow(x,y)                  --> int
    ! readln(n,path$)           --> string,V0
    ! replace(a$,find$,text)    --> string
    ! reverse(a$)               --> string
    ! insert(a$,pos,text)       --> string
    ! right(a$,length)          --> string
    ! split(a$,delim,array$[])  --> int
    ! rnd(n)                    --> int
    ! spc(n)                    --> string
    ! str(n)                    --> string
    ! tick(n)                   --> int
    ! trim(a$)                  --> string
    ! ucase(a$)                 --> string
    ! val(a$)                   --> int


    n=val("510")/2              ! returns 255
    n=asc("hello")              ! returns 104 (ASCII of "h")
    n=find("abcdefg","de")      ! returns 4
    a$=chr(65)                  ! returns "A"
    a$="0x"+ucase(hex(255))     ! returns "0xFF"
    a$=right("Hello",2)         ! returns "lo"
    a$=lcase("HELP Me")         ! returns "help me"
    a$=path(0)                  ! returns HB path (e.g., "C:\HB")
    do:wait 100:until key(27)   ! waits until key Esc is pressed

In the file Console.asm I see "Copyright © 2013-2015, Nick Kouvaris". Is this the same Nick Kouvaris, which did flash games on lightforce.freestuff.gr?

A user-defined function returns an integer value. A variable can be passed
by value as a parameter to the function. Local variables declared within
the function can only be used by this function.

Code:
    sub addition(a,b)    ! function declaration

        local sum        ! local variable declaration

        sum = a+b

        rets sum         ! return value

    ends                 ! function end


    input "Enter number 1:",a
    input "Enter number 2:",b

    sum = addition(a,b)  ! function call

    print "Output:",sum
    pause

A tiny set of UDP network functions is available to send and receive messages
using a connectionless UDP socket. When such a socket is created, all incoming
UDP messages are placed in the waiting stack (queue) and accessed according
to the first-in first-out (FIFO) principle.

Code:
    ! create UDP socket
    ! n=open(port)                --> int,V0

    ! send data through socket     
    ! n=send(ip$,port,data$)      --> int
  
    ! pop the queue
    ! a$=queue(0)                 --> string

    ! peek the queue
    ! a$=queue(1)                 --> string

    ! get queue info
    ! a$=queue(2)                 --> string [IP PORT LENGTH TIME]
        
    ! close connection
    ! n=close()                   --> int

I/O operations in Hobby Basic.

Code:
    ! file path$,a$,0          save string as text file
    ! file path$,a$,1          load text file to string
    ! file path$,a$,2          append string to end of file
    ! file path$,array[],0     save array as binary file
    ! file path$,array[],1     load binary file to array
    ! file path$,array[],2     append data to end of file
    ! file path$,0,0           create empty file
    ! file URL$,0,1            download URL
    ! file URL$,0,2            download URL w/o feedback
    ! file path$,0,3           delete file
    


Code:
    input "Write some text:",a$

    ! save string as text file
    path$=path(0)+"\a.txt"
    file path$,a$,0

    ! print file size
    print path$," ",size(path$)," bytes"
    pause
    


Code:
    ! create a com executable (16 byte DOS demo)
    dim a[4]=0x10CD13B0,0xC81107C4,0x40FBE2AA,0x94E1F8E2
    file "a.com",a[],0
    end

I uploaded a new version 0.79 with many small improvments and bug fixes. I tried the interpreter with success in Windows XP/7/8 32/64 bit, Wine (Linux). I removed the Win32 Console Library source code from inside the zip. It was an old version which was last updated 3 years ago. Hobby Basic is now using a newer version.
