File problem

[tenochtitlanuk]

Wrote ( in LB5) code for a poster on JB forum and it fails
open "test.fil" for input as #fIn
   content$ =input$( #fIn, lof( #fIn))
close #fIn

Runs fine in LB4.. is there a syntax change??

[Carl Gundel]

It fails how exactly?

I think I've mentioned this problem with reading a file with LOF in a couple of my posts:


filedialog "Open .bas file", "*.bas", fileName$
open fileName$ for input as #f
   txt$=input$(#f, lof(#f))
   close #f


error log:

I want to guess, something related to LOF? Something not yet implemented?

[tenochtitlanuk]

Obviously, since the prog. is quite happy if file exists and you use the known length-of-file rather than LOF!!

Hi John, I was trying to understand the Error log, that is why I'm guessing. I did not test the code yet.
