[Gambas-user] Write to file is adding strange characters

[nando]

When you use the WRITE statement, there are two ways to use it:
1)  WRITE #hFile, test
2)  WRITE #hFile, test, LEN(test)

Explanation...

1) Gambas adds the length of the string as part of the written data.
   This one will cause you problems because it adds lenght automatically.
2) Gambas adds nothing and writes only the quantity of bytes 
   specified by LEN(test) WITHOUT adding anything else to the file.

Use 2) by adding   ,LEN(string var) and the file will be as you expect.
