FDISPLAY fdisplay(string format_str {, integer | real | string argument}) : integer;

Displays the format string with all the arguments at the current cursor position. There

should be a one-to-one correspondence between the format control characters in the

format string and the arguments provided. If an argument provided does not match

the corresponding format control character it is ignored in the conversion. The

number of arguments converted is returned. For a detailed description of the format

control characters, see “Format String and Format Control Characters” on page 151.

Example

/* This script illustrates the fdisplay command. */

proc main;

string date_str;

string time_str;

display("Example for fdisplay command^J^M");

date(date_str);

time(time_str);

fdisplay("Current date is : %s, time is : %s^J^M", date_str,

➥ time_str);
