Hi MajorDill,

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

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

Hello World

^^Thank you fasmnewbie.

The 'Hello World' program in Hobby Basic.

Code:

    cls
    for i=1 to 15
        pen i
        locate i,i
        print "Hello World!"
    next i
    inkey

Drawing text is easy with Hobby Basic.

Code:

   screen 80,25

    cls 
    for y=0 to 24 
        for x=0 to 79 
            pen (x+y)/16

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.

Hobby Basic Examples

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

Hobby Basic Functions

A set of built-in functions is available. These functions always return either an integer value or a string.
A variable that will store the return value must precede the function 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
    ! 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"
    print lcase("HELP Me")      ! prints "help me"
    do:wait 1:until key(27)<>0  ! waits until key Esc is pressed





User-defined functions are now supported (version 0.96 January 2018).
An integer variable can be passed (by value) as parameter to a function.
A variable that will store the return value must precede the function call.


Addition of two numbers.

Code:

input "Enter number 1: ",x
input "Enter number 2: ",y
 
res = addition(x,y)  ! function call
 
print "Output: ",res
pause
 
 
sub addition(a,b)  ! function declaration
 
    local sum      ! local variable declaration
 
    sum = a + b
 
    rets sum       ! return value
 
ends               ! function end





Factorial using recursion.

Code:

sub factorial(n)
 
    if n < 1
        rets 1
    else
        rets n*factorial(n-1)
    endif
 
ends
 
 
n = 10
print "Factorial of ",n," is ",factorial(n)
pause

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?

Hobby Basic Labels

A label is identified by the symbol # at the end of a string. Comments inside 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




Code:

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

  L1print "Label 1":return
  L2print "Label 2":return
  L3print "Label 3":return




Anonymous Labels.

Code:

  @@#

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

  goto @b

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.
