FINDNEXT findnext(var string file_name) : integer;

If there is a matching next file/directory for the given pattern, file_name is updated;

otherwise it is not updated. If there is a next file/directory the return value is 1, else it

is 0.

Example

See findfirst command.

FLOOR floor(real float_no) : integer;

Rounds down float_no to the next integer (if the value is already an integer, its value

is returned). For example, 1023.23 is returned as 1023; -1023.23 is returned as -1024.

Example

/* This script illustrates the floor command. */

proc main;

real x;

x = 1023.23;

fdisplay("floor(%f) is : %d^J^M", x, floor(x));

x = -1023.23;

fdisplay("floor(%f) is : %d^J^M", x, floor(x));

endproc

FOPEN fopen(string file_name [, string open_mode | integer open_mode]) : integer;

Opens file_name. The mode in which the file should be opened is specified by

open_mode. If open_mode is not specified, it is assumed to be read/write mode. If a

string argument is given for open_mode, it should be either readonly or readwrite; any

other value will fail the command. If open_mode is an integer, it should match the val-

ues accepted in the DOS Int 21 Fn 3Dh. (I.e., the value should be a valid open mode as

understood by DOS. If the value is not a valid one, it could lead to unpredictable be-

havior). If the file is opened, the predefined variable EOF is set and the file handle is

returned; otherwise -1 is returned.

Example

See fcreate command.

FPUTC fputc(integer file_handle, string buffer) : integer;

Writes the first character from the buffer to the file given by the file_handle. Returns the

number of bytes written to the file. If an invalid file handle is passed the command is

ignored and 0 is returned.

Example

See fcreate command.
