READSTR error

[Neurox]

Hi,

I've used the Readstr command :

Code (glbasic) Select Expand

READSTR 1,wRiffID$,4but the compiler tell me :

Code (glbasic) Select Expand

GPC - GLBasic Precompiler V.2007.159 - 3D, NET
"GP2XInitSound.gbas"(178) error : wrong number or aguments : "READSTR" called with 3 args. Required: 2Why :-(
Well I removed the last parameters,
and code is  :

Code (glbasic) Select Expand

READSTR 1,wRiffID$but the result is :

Code (glbasic) Select Expand

This problem is still present in the current version of the compiler. I'm facing the same problem now

But there's another way to save and read strings from files. It is also shown in the example for OPENFILE in the GLBasic help.

You can use READLINE instead of READSTR. Therefor you will have to add a newline command at the end of every string to be saved.

Here's a short example on how to use it:

Code (glbasic) Select Expand

// store some data into the test file
OPENFILE(1, "test.dat", FALSE)
WRITELONG 1, 1230
WRITESTR 1, "a test line\n"
WRITESTR 1, "two lines\nat a time\n"
WRITELONG 1, 578
CLOSEFILE 1


// open testfile and show the data
OPENFILE(1, "test.dat", TRUE)

READLONG 1, num1   // will read 1230
READLINE 1, s1$    // will read "a test line"
READLINE 1, s2$    // will read "tow lines"
READLINE 1, s3$    // will read "at a time"
READLONG 1, num2   // will read 578

PRINT num1, 0, 20
PRINT s1$, 0, 30
PRINT s2$, 0, 40
PRINT s3$, 0, 50
PRINT num2, 0, 60
