FCREATE fcreate(string file_name) : integer;

Creates the file given in file_name. File_name can include the drive letter and path. If

the file is created, 1 is returned; otherwise 0 is returned. If the file is created, it is

closed and will have to be opened by an fopen call to access it.

Example

/* This script file illustrates fcreate, fopen, fread, */

/* fwrite, fputs, fputc, fgets, fgetc, and fclose commands. */

proc main;

string file_name;

string test_string;

string str;

integer len;

integer count;

integer file_handle;

integer position;

integer offset;

integer origin;

file_name = "tempfile";

if fcreate(file_name) then

fdisplay("%s created^J^M", file_name);

else

fdisplay("%s could not be created^J^M", file_name);

goto error_exit;

endif

/* open the file in read/write mode.*/

file_handle = fopen(file_name, "READWRITE");

if file_handle >= 0 then

fdisplay("%s opened^J^M", file_name);

else

fdisplay("%s could not be opened^J^M");

goto error_exit;

endif

test_string = "example string";

if fputs(file_handle, test_string) then

fdisplay("fputs done^J^M");

else

fdisplay("fputs failed^J^M");

goto error_exit;

endif

if fputc(file_handle, "a") then

fdisplay("fputc done^J^M");

else

fdisplay("fputc failed^J^M");

goto error_exit;

endif

len=4;

if fwrite(file_handle, test_string, len) then

fdisplay("fwrite done^J^M");

else

fdisplay("fwrite failed^J^M");

goto error_exit;

endif

fclose(file_handle);

/* close the file. */

/* open the file in read/write mode. */

file_handle = fopen(file_name, "READWRITE");

if file_handle >= 0 then

fdisplay("%s opened^J^M", file_name);

else

fdisplay("%s could not be opened^J^M", file_name);

goto error_exit;

endif

/* read in characters into a string. */

if fgets(file_handle, str, 3) then

fdisplay("fgets done, string read is :%s^J^M", str);

else
