I tend to agree with speedfixer, use option #1. (preferred) Also, just providing ' primitives ' like required Macro's and such, should do. Extending the 'primitives' according to the ' job at hand ', by the application developer, at the sole discretion of the programmer in question ... I'd strictly ...

@dodicat,

file is small: 2.53 MB only, otherwise, all okay. (FBC 64, 1.06.0, Win standalone)

This feature enabled, my life is easier ;) What makes you think so? I don't see any reason for it. 'Var bar = 67.2f ' forced to: Single Var bar = 67.2 ' default Double #Print TypeOf(bar) ' see: compiler output Print bar : Sleep TypeOf() returns the data-type, as string at compile time.

Thank you.

When the data are referenced by a pointer, alone or within a descriptive structure (a UDT, for example), it is usually best to only SWAP only exchange s the values of the pointers or the contents of the descriptive structures without accessing data themselves. This part needs a reformulation, a sta...

Result: H€llΩ 8 H€llΩ 5 As seen above len(String) contains 8 (UByte) while len(WString) contains 5 (UShort?), which indicates, that *..IX* systems use UTF-8 (as standard) which is a very different system, looking at it from a DOS/WIN perspective (ASCII/ANSI) ... (Btw. not certain, that WString on *...

Thumbs up, full marks, thanks ... just use *generally" as first word (after NOTE:)
by simply deleting "more"

Perhaps: Note: For var-len strings, Swap is more efficient than a classical exchange by circular assignments (using a third temporary string), because only the strings descriptors are exchanged rather than all strings data characters. More generally, when the data are referenced by a pointer, alone...

Your Poposal: -> OK, for String I'd like you, however, to add something like: The same applies to Ptr's, even in UDT's (Ptr's swapped, no change to 'pointed to' values). <OT> just had a server failure (trying to post): 503 Service Unavailable The server is temporarily busy, try again later! </OT>

I think that misunderstanding on this subject is definitive between us. OK, i'll try, one more time: the left / right columns of results proof nothing, because: the comparison should be: String vs. Type (identical to String) both with Swap , which I expect to result in: equality (more or less) you'...

swap time proxy time str: 0.006706200074404478 0.05453830002807081 So you see no improvement between the left column and the right column? Absolutely pointless question because: compare: apples with apples to do that, the current testing code is useless. What does useless test code proof? (rhetoric...

The difference is that a string is an object with a Let operator Let that copies the string data characters when assignment is called, which is not the case of an UDT containing a pointer to data block. Sorry, but this is nonsense because, the DATA isn't touched at all, just the Ptr's adresses need...

Sorry, doesn't make the tiniest bit of sense, by cons, it's just illogical, at least as long, as you can't describe the very details of optimizing, that is "supposedly" taking place ... A Ptr in a UDT "u" and, a Ptr in the UDT "String", is "the same difference"...

KeyPgSwap → fxm [Added a note that what Swap is optimized for var-len strings] This is not exactly the whole truth, because it applies likewise, to PTR's in UDT's (any data-type or UDT), where the allocated memory is always external to the UDT itself (only the PTR's size is allocated, inside the UD...
