Fastest way to find a string in a file with PBDOS?

[Wayne Diamond Member Find all posts View Profile Close Wayne Diamond]

Can somebody please help me, Im having great difficulties with this in PBDOS, but its very easy in PBDLL/PBCC... all I want to do is look for a string in a file

In PBDLL or PBCC Id use something like this:

Dim FileData$
Open FileName$ For Binary Access Read As #1
 FileData$ = Space$(LOF(1))
 Get #1, 1, FileData
Close #1
StringPosition = Instr(1, FileData$, "string to search for")

In PBDOS im being limited to 32kb strings so its thrown a spanner into the works!
Anyone ?
Thanks in advance, this one has really got me stumped and I can't proceed until I get this sorted out

Hi,

You can use in pb3.5 virtual strings -but they are -very- slow.

The best way is to pick up file-sticks between 1 - 32 kb in

a logical way - beware of the end of line bzw. the lenght of

the record to cut the chunks not between a word.


Next step is to search in this string for the result. Then

read in the next and so on ... until you find it.


I´ve found, that a smaller 'get-in-string' between 1-5 kb is

faster then the full lenght of 32 kb.
