ugBASIC forum

[italian and french follow] :arrow: english Good morning everyone! I'm not entirely sure it is a bug. The problem involves a form of "relaxation" of the syntax with the GLOBAL command. I'll explain. The GLOBAL command allows you to tell ugBASIC to consider a variable as "global"...

Hi ldir_hector ! I use enable peephole optimizations up to 16 passes and enable listing and enable additional info. Does this options increase the compilation time ? Surely, the option for additional information slows down the compilation a lot. It actually depends on the size of the generated assem...

Hi ldir_hector ! I'm sorry but I don't understand the N in BR2NR4D4R4UL2 The N command has the meaning of no update of drawing position. This is to draw a line as specified but do not use the end of the line as the new position. So, NR4D4 means: "draw a line of 4 pixel on the right ( R4 ), go b...

AFAIK, it is possible on some dialects, like BBC BASIC.

Yeah, but it is more verbose.

Hi everybody, and thank you for your interesting answers! :D I remind everyone that we are looking for an isomorphic approach to the problem. This means that we are not looking for a "lowest common multiple" but rather a way to best express the potential of each target. For me, the file me...

[italian and french follow] :arrow: english Hi everybody! Ok, as you well know, I've been asked for some time to add support for storage devices, i.e. mass storage. Apart from the fact that I opened an issue about it , in general it involves giving support to four different things: give the possibi...

Hi ldir_hector , thank you for the message and... well, program chaining... my forbidden dream! 8-) On the Amstrad CPC standard basic, the only way to jump on a line number contained in a variable was by the CHAIN MERGE "prog.bas",lineNumber% method. This is quite interesting. In the sense...

[italian and french follows] :arrow: english Hi everyone! Recently, I implemented a mechanism for dynamic RESTORE . In short, instead of using a label or a line number, you can use a variable (provided it is defined and valued) to indicate (yes!) the line number from which to start reading the data...

Hi ldir_hector , wow, that's a very creative way to leverage ugBASIC and measure time! :D The time unit is 1/50 second which is quite precise, but the Amstrad CPC is able to do better ! It almost makes me want to add a "raw" timer, i.e. the possibility of actually reading the real timer of...

Someone asked if this command execute faster than several draws instructions or is it just a syntaxic shortcut. So, let's assume that the code is written in Median language (sorry, I couldn't find a better name). The Median language is a sort of "portable assembly", a cross between pure an...
