reading file error
Post by pierscintilla on May 28th, 2013, 12:00pm

Hi.
I started using LBB to convert some programs that I wrote in LB4 with the aim of testing the potential of BBC that I look very good!
I have a problem with the following code to reading text file of about 200Kb.

code:
open "c:\text.txt" for input as #1
txt$ = input$(#1, lof(#1))
'print txt$
close #1

translated code:
HIMEM = PAGE + 70000000
INSTALL @lib$+"LBLIBC" : PROC_LBinit : lc%=0
3 `1 = FN_open("c:\text.txt", 1)
4 txt$ = FN_getby(`1, FN_ulong(EXT#`1))
11 CLOSE #`1

I get a message INPUT $ too long at line 0

There is a possibility of solution?
What code I could use the BBC to get the same thing?

Many thanks in advance

I tried the same translated code with the BBC (trial) and when I launch the program I get an error "NO ROOM". is due to the limitation of the trial?
Thanks

What version of LBB are you running? The current release version (1.87) will give that error because it has a string-length limitation of 64 Kbytes. The beta test version (currently 2.0.0.5) should work OK because it has no such limitation.

The most straightforward thing for you to do is to wait until LBB v2.00 is released, which I expect to be in about two weeks time.

Richard.

Ok. I am running the 1.87 ver.

Instead, for the error "NO ROOM" in BBC is due to the limitations of the trial version?

Thanks

Almost certainly. The trial version provides only a maximum of 12Kbytes for program+data+stack.

LBB will allow you to run BBC BASIC code, to a degree, by prefixing each line with a ! character. That causes the code to be passed straight through the LB-to-BBC translator. Using that 'trick' you may be able to test some simple BBC BASIC code without the limitations of the trial version.

If you want to join the group of beta testers for LBB v2.00 send me a private message.
