#CRLF$ as StringField delimiter

[MachineCode]

I see in the manual that StringField's delimiter can only be one character. But, this works with #CRLF$. Why?

Code: Select all

Debug Len(#CRLF$) ; Returns 2

a$="123"+#CRLF$+"456"+#CRLF$+"789"

For i=1 To CountString(a$,#CRLF$)+1
  Debug StringField(a$,i,#CRLF$)
Next

Delimiter$ The string delimiter to use to separte the fields. It can be a multi-characters delimiter.

But it works with PB4.10+

Interesting! But I'm still using 5.00 at the moment, so I never saw the new manual change.

[ts-soft]

Only tested with your example, so please have attention!

I assume always we talk about latest final, stable versions. If you speak about any older version, it would be helpful to mention it.
Who cares about Version 4.10, it is over 5 years old?

It's considered 'final' and 'stable' if there is no 'beta' in the name. Of course, there will be always new versions, even after 5.11...

[MachineCode]

Without looking at the manual (since 5.10 is not installed ATM), does LTrim() and RTrim() support multi-character removal too?

'Character$' has to be a one character length string

Where have you your eyes? PB4.10+ means all Versions, since PB4.10.

MachineCode speaks over <= PB5.00, this can you see, as he mentioned, this is not in the helpfile.

"Not in the helpfile" means it is not officially supported by version 5.0 he is using. It is like the new 'string.s + i.i' feature - still experimental (means: not working correctly in all cases) and not mentioned in the manual,
not mentioned in the history.
For serious applications and games development you always should rely exactly on the manuals, whether it is PB, MSDN, Apple Developer Central.
Read the text twice and follow it exactly. Other information are not reliable, it is just trial and error. Just works? Good luck with your business!

Hi,

I'm not sure if it works:

#CRLF$ can be detected with the first character #CR
The #LF is not always displayed with Debug.

To test if it works with mutiple charactres you need to test it with something like that:

String: "ABCDEFCDGHIJCDKLMN"
And "CD" as delimiter.

Sorry I can not test it, I removed the old stuff completely

Do you mean this feature isn't mentioned? If so, check this out:

- Added: autocast of numeric values when string are involved, allowing to concatenate string and numeric in constants

Yes, this is exactly what I meant. It is mentioned in the history in this case (thank you!), ...[removed blah blah]

As seen in the changelog, the CRLF works from version 5.10 on (and LF has been ignored in all PB versions up to version 5.00)

Code: Select all

a$="123"+#CRLF$+"456"+#CRLF$+"789"

For i=1 To CountString(a$,#CRLF$)+1
	s.s=StringField(a$,i,#CRLF$)
	Debug Str(Asc(s))+" / "+Str(Asc(Trim(s,#LF$)))+" : "+s+" / "+Mid(s,2,3<<4)
