Hi Again,

Change the 'wait' multiplier to 0.1 on Supergoldcard.... to get the sound right.

Fireworks2_bas was first writtten on QPC at 1.8Ghz, then on Qemulator....

On a 128ko QL, experiment with the wait factor !

Regards,

Steve.

Weird but I ran this on QLAY2 and it corrupts itself (i.e. the BASIC gets corrupted).

Hi Bwinkel67,

I don't have QLAY... but have examined the fireworks code, and guess at your bug solution.....

First you mention corruption : Do you get the MIStake keyword inserted, and if so on which lines ?

The type of the formal parameter 'wait' depends on the first calling parameter, the literal 22222, so is integer.

22222*.5 is 11111, also integer. The second call gets 999*.5.... 499.5 which is float ! (The FOR loop is float too...)

If QLAY baulks with the value 77777*.5, it means that QLAY is expecting an integer maximum of 32767 !

Normally, the QL allows coercion in such cases, but maybe QLAY doesn't here? (Try changing 77777 to 32767).

But as I said, I can only guess without having QLAY to experiment with !

Best wishes,

Steve.

No, I mean corrupts memory where part of the loaded code becomes gobbledygook.

If I save the basic code after running it, here is what it looks like:

Hi Bwinkel67,

Line 420 has the statement INK ik,ik+4,3, where ik+4 can take the value 255+4. ( SMSQ/E converts this within range using MOD. )

So, try changing line 240 to read inc=RND(251) . ( QDOS does not do range checking and conversion, it would appear ).

But I am at a loss to see why that would corrupt the ' OVER ' entry in the name-table to ' ÿVER ' !

Hope this fix will work though...

Steve.

Depending on the ROM version used, QLAY might simply crash/corrupt the program because of too many LOCale variables in the procedures.
Weird things happen on older (older than JS) ROMs (even on "real" QLs) when more than eight local variables are used.

Using Minerva ROM on the emulator would cure that.

So using Minerva got rid of the corruption but it now crashes at line 420:

At line 420;3
bad parameter

I tried steve's hack and still got the same error. At least it's not corrupting anymore.

This is a polite request!

Gents, you have hijacked the "Happy Birthday" thread. Would it be better to continue this conversation on a new thread? This will help to avoid confusing us old folks who come here looking for good news, happiness and to see who is catching us up in the age stakes!

(Said the old git!)
