[6.12 LTS - Win x64] FindString() - False Result

Code: Select all
txt$ = "what-the-foo"
count = FindString(txt$,"-")
Debug count
Result = 5 [false]
Code: Select all
txt$ = "Iiiii-like-purebasic"
count = FindString(txt$,"-")
Debug count
Result = 6 [false]
Error seems to be in first string part:
Code: Select all
txt$ = "w-the-foo"
count = FindString(txt$,"-")
Debug count
Result = 2 [true]
Code: Select all
txt$ = "I-like-purebasic"
count = FindString(txt$,"-")
Debug count
Result = 2 [true]
Cheers

Why is that false? The first dash is indeed position 5. Not a bug.

Sorry, I confused CountString with FindString.
I have problems to switch between programming in javascript and purebasic.
it's too different - and i'm getting old.

Easy enough to confuse, generally post in questions before bugs as it's often the case of users error than bug.
and opps I just sent a pm for the same reason of getting old! clicked the wrong button!

The big difference between javascript and purebasic, it is the speed.
I think you can search a byte code in 100 megabytes in javascript, while you can search a byte code in one gigabyte in purebasic.
This difference can bring some motivation to learn. Here is a clock which details about the time resolution in purebasic.
Code: Select all
Procedure CLK()
! RDTSC
ProcedureReturn
EndProcedure
Debug CLK()
Debuh CLK()

Olli :
"debuh" = error

I'm interested in how the clock counter is being returned by ProcedureReturn.

" ! RDTSC" places the result in edx and eax on x86 and for x64 it combines them in one register
"ProcedureReturn", as per the pb manual:
Code: Select all
If no value is specified for ProcedureReturn, the return value will be zero if the compiler uses the C backend and for all processors managed by PureBasic, or the content of the 'eax' register in 32 bits (X86 processors) or 'rax' in 64 bits (X64 processors) if the compiler uses the ASM back-end, (see for more information).
That's one thing about PB, you really have to read the manual
