FOPEN_ program instruction Open the file named data.dat on the default device for read-only access with variable-length records (record length omitted). Since the mode parameter is omitted, prereads will occur and the records will be accessed sequentially (which is required for variable-length records). FOPENW (5, 32, 3) "D:x.d" Open the file named x.d on the device D for read-write access using fixed-length records of 32 characters each. The mode value 3 has both bits 1 and 2 set; thus, prereads are to be disabled and random access is to be used. FOPEND (5) "*.dat" Open the current default directory to find all the files with the extension DAT.
