byref or not byref that is the question.

When working with strings in PB does the ParseSTRING make a local copy or am I working from original data.

simple example of what i mean.

[code=thinbasic] '----------------------------------------------------------------------------
FUNCTION Exec_TBZZ_String2String() AS LONG
' load a bitmap.
' Usage: n = TBZZ_String2String ( StringtoCopy, StringCOPY as STRING)
'----------------------------------------------------------------------------

LOCAL String1 AS STRING
LOCAL String2 AS STRING

IF thinBasic_CheckOpenParens() THEN
thinBasic_ParseSTRING String1
IF thinBasic_CheckComma() THEN
thinBasic_ParseSTRING String2
IF thinBasic_CheckCloseParens() THEN

string2 = string1


END IF
END IF
END IF

END FUNCTION
[/code]

Abraxas,

in your example, all strings are local.
[code=thinbasic]

thinBasic_ParseSTRING String1

[/code]
Get a string from the script and make a local module copy.
The same in
[code=thinbasic]

thinBasic_ParseSTRING String2

[/code]

To return a modified string you can use the function name. Declare function AS STRING, define in your LoadLocalSymbols something like:
[code=thinbasic]

thinBasic_LoadSymbol "TBZZ_String2String" , %thinBasic_ReturnString , CodePtr(Exec_TBZZ_String2String ), %thinBasic_ForceOverWrite

[/code]
and inside your function something like:
[code=thinbasic]

FUNCTION = String1

[/code]
or whatever you want to return.

Instead, if you want to have a parameter passed BYREF to your module function, please have a look at this post here: http://community.thinbasic.com/index...sg4452#msg4452

If you need more info, let me know and I will give all the info you need. I'm going home from work right now so please excuse me if I will reply a bit later.

Ciao

Is this information still valid or has it been replaced with something new?

I was wanting to byref a string.
