[?] loading files

[tomchi]

Hi,

In order to reduce RAM usage of a game I'm (once every 2 years ) working on, heavy usage of BLOAD makes it crash. Older version of the game using inlines works ok.

I know FILESELECT is kind of buggy when it comes to do nasty stuffs, if one can consider MALLOC is a nasty command

So, here's what I do, can't post the complete source of the game indeed :

in the init proc :

Code: Tout sélectionner

  ' DETERMINE LE CHEMIN COURANT POUR LE PROG APRES COMPILE
  chemin$=CHR$(GEMDOS(25)+65)+":"+DIR$(0)+"\"


then when a file is needed, just call a proc this way:

Code: Tout sélectionner

@charge("blah.sht",place%)


Code: Tout sélectionner

 > PROCEDURE charge(fichier$,emplacement%)
  oussa$=chemin$+"datas.rz\"+fichier$+chr$(0)
'cmd$=chr$(0)
'env$=chr$(0)+chr$(0)
'bp%=gemdos(63,L:V:oussa$,L:flong%)
  BLOAD oussa$,emplacement%
RETURN


It all works well twice= loading menu, menu runs, select something, load files, run the something, load menu files, run menu *2
and then it doesn't want to load anymore. Checked as many things as i can inside the code, seems ther's no mistake left.

Then, I made the prog just loop the menu : load menu files, run menu, select something, load menu files, run menu
And I still got the same prob.

So wether there's an error in the code i can't find, wether BLOAD ain't that rock solid command.

I also tried with OPEN/BGET , still same prob. As you can see in the above code, I'm about to go into gemdos call but, damn i don't know how to do / not sure it will work better.

As anyone experienced something like that ? Any idea ?

Thx

Are you very sure that the buffer area you load it into is large enough? If it happens to be to small, weird problems can occur.

reading your answer, i understand that BLOAD may not be faulty, that means i introduced a bug i spent hours tracking without finding it ...

gonna check this and maybe raise the reserve amount

[tomchi]

POINT !

Thx lonny, you were right, raised reserve and could make more loops, then checked for something like DIM and found i called a proc each time in which was something like text$=text$+"blah" .....

As-tu utiliser Reserve avant de faire des Malloc, faut pas oublier que l'interpreteur utilise de la memoire , mais bon si tu utilise une machine de 4 mo ca ne devrait pas poser de probleme reste a savoir si le GFA a prévue cela , c'est quel version ?

A l'epoque quand j'ai commencer je n'avais que 512 mo , du coup j'ai vite abandonner malloc et fait des trucs pas propre , je reserver ma memoire en partant de l'adresse video et en soustrayant mes buffers , en esperant ne pas marcher sur l'interpreteur

je te rassures, MALLOC et RESERVE sont mes amis, j'ai appris à bien les utiliser, comme je disais à lonny, l'erreur s'était glissée dans la definition d'une chaine de caractères à laquelle à chaque appel au menu je rajoutai de la longueur, mais l'erreur est fixée depuis longtemps, enfin disons que j'en suis à règler d'autres bugs
