I can't do much at the moment other than leave it as is, or disable it.
There's more ways to the interpreter for the downloading and running a program located on a remote server. Code:
url$ = 'https://sites.google.com/site/hobbybasicfiles/TEST.BAS'
Code:
load url$,1
if V0 = -1 then ? 'load error' : end
run 'TEST.BAS'
or even Code:
run url$
get the source code Code:
a$ = GETSRC(url$)
I have uploaded a new version with minor improvements and bug fixes. A console breakout game (with sounds) included in the examples.  Last edited by Picnic on 22 Jan 2022, 08:39; edited 4 times in total |

Hi all,
I have uploaded a new version with minor improvements and bug fixes. Smaller executable size. The wait command return to milliseconds. The time measurement in microseconds was abandoned. The SPC() function has been removed since the more flexible GEN() function now exists. Improved error messages. A point that I have neglected and HB suffers from. It still needs work but it's much better now. Small internal changes made the interpreter some ms faster overall in my measurements. Minor bug fixes. The interpreter works consistently on Windows XP, 7 and 10. Includes all programs presented in previous posts. The previous version of the Trim(string$) funtion was removing the whitespace and newline characters (0x9,0x20,0xA,0xD) simultaneously left and right on a string but without the option to select a side. The new syntax of the command is Trim(n,string). The values obtained by the variable n are 0, 1 and 2, for TrimLR, TrimL and TrimR respectively. Enum command is also added. More information and examples have been added to the README file. 9/7/2021 - A silent update to version 1.2.1 concerning a fix at the internal ANSI interpreter module. A new command SCROLL is now available which scrolls the console screen buffer up or down, plus some new code examples. 18/7/2021 - A silent update to version 1.2.3. Small internal changes increase stability in Windows 10. Hobby BASIC now runs better on newer versions of Windows, but remains just as functional on XP. The version additions concern the SET command and a new function MATCH (arg, arg_list, ...). More demos has been added and the README file updated with the latest information. 8/8/2021 - A silent update to version 1.2.4. Passing arguments by reference is now possible. To pass an argument by reference, use 'byref' keyword before the argument on the subroutine call. Still under testing though. Also, some bug fixes made. Passing arguments by value and by reference. Code:
sub foo(var,string$,array[])
ends
foo(x,a$,a[]) ! by value
foo(byref x, byref a$, byref a[]) ! by reference
Passing arguments by value and by reference example. Code:
a = 100
b = 200
print "Before swap, value of a: ",a
print "Before swap, value of b: ",b
swap(byref a, byref b)
print "After swap, value of a: ",a
print "After swap, value of b: ",b
end
sub swap(x,y)
local temp
temp = x
x = y
y = temp
ends
Select..Case..Endsel has been added. Code:
x = 1
select x
case 1:
? "Choice is 1"
case 2:
? "Choice is 2"
case 3:
? "Choice is 3"
case :
? "Choice is other than 1,2, or 3"
endsel
Text Draw was updated in version 0.5 after some time. It now works more stable (especially in Windows 7) and some new features have been added. I will show you what it can do now. I am opening an ANSI file. We can paint using the character set. We can change the colors of the image, rotate image, cut it into pieces. Make copies of the pieces, or insert a new image. Open long static ANSI images switching from one frame to another. Text Draw converts an ANSI image to .HB format (always the screen we see) and saves 2 files. One in the dimension 80x50 and one smaller in the dimension 80x25 (the classic size of the old ANSI files). 
Pressing F10 the interpreter does the conversion and exports a loader script. 
Bugs and small problems exist. I used google translate. Last edited by Picnic on 27 Apr 2022, 08:06; edited 14 times in total |
