... will setting the string to null return its memory to the heap? Yes, using msvcrt.free, which in turn uses RtlFreeHeap I know it's difficult to use an assembly level debugger, but what I wrote is the truth, and you won't get the truth from FRE(). However, if you insert a Sleep as shown below, yo...

There is nothing to optimise: These are obviously addresses.

So what? They are addresses, as adeyblue rightly noticed.

Data Compression Explained by Matt Mahoney Matt is definitely a top expert in the field. Anybody who seriously wants to start with compression should consult his site. Another site to consult: https://www.maximumcompression.com/data/summary_mf.php (sort by efficiency - I use FreeArc, in spite of so...

I've tried only a handful, they all worked. Maybe you should change your general approach? Reading instead of writing, for example?

Nice code, xywhsoft! Here is some code for getting the time to load a textfile into a string array using s2=Split(pContent, chr(13, 10)) : #include "recall.bi" #include "windows.bi" #include "crt.bi" ' Global variable, used to save the number of returned split strings D...

How do I install a Library to FBIDE? Hi Ivan, As an example, the Cairo library would sit in two locations: C:\MyBasics\FreeBasic\lib\win32\Cairo\*.dll C:\MyBasics\FreeBasic\inc\Cairo\*.bi Once the necessary files sit there, you can compile e.g. C:\MyBasics\FreeBasic\lib\win32\Cairo\line.bas (if you...

Yes 'memcpy' may induce an undefined behavior although the compiler can easily determine in which direction to copy so as not to overlap (and it usually does), but it may also depend on the optimizations applied. 'memmove' guarantees everything. So replace 'memcpy' (the seco...

What about adding elementInsert to the core FB language? See FreeBasic Insert string into array : Comparing MasmBasic's Insert against the respective FB macro written by fxm : elementInsert (array, index, element) is only marginally slower than Insert array(), index, element :thumbsup: The executabl...

Sounds suspiciously close to a linked list ;-)

For string arrays: Insert, Delete, QSort, Recall, Store and many others; press Ctrl F in that page and search for Array

Another option would be to load the array with data as strings 1...17, then to insert the empty strings: Read sAttnam() Insert sAttnam(14), 169 ' insert 169 empty strings; see Insert() Insert sAttnam(185), 69 I searched the FB manual but could not find an INSERT ...
