Maximum Number of Bytes Read Using Low-Level Functions

MORE INFORMATION

The number of bytes read is for a single command only, which means a file of greater size can be read but the number of bytes read at one time can not exceed 65,535. This can be demonstrated with the following example. After the error message is generated, the user may choose Ignore to continue with the program execution.

   mchan=FOPEN("C:\any_large_file",12)
   ? FREAD(mchan,65536)
   *error message number 11 generated
   ? FGETS(mchan,65536)
   *error message number 11 generated
   ? FREAD(mchan,65535)
   * or
   ? FGETS(mchan,65535)
   * no error is generated
   ? FCLOSE(mchan)
