STRCMP strcmp(string first_string, second_string) : integer;

Compares first_string to second_string. If they are the same, 0 is returned. If first_string

is less than second_string (i.e., earlier in the alphabet or number line), a negative value

is returned; otherwise a positive value is returned.

Example

See strlen command.

STRCPY strcpy(var string target_string, source_string);

Copies source_string to target_string. If there is any error in copying, 0 is returned;

otherwise 1 is returned.

Example

See strlen command.

STRFMT strfmt(var string buffer, string format_string {, integer | real | string argument})

➥ : integer;

Formats the arguments according to format_string and copies to buffer. There should

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

string and the provided arguments. If a provided argument does not match the cor-

responding format control character, it is ignored in the conversion. The number of

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

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

Example

See strlen command.

STRLEN strlen(string buffer) : integer;

Returns the string length of buffer.

Example

/* This script illustrates the strlen, strcat, strcmp, */

/* strcpy, and strfmt commands. */

proc main;

string str;

string tail;

string str1;

string str2;

str = "test string";

display("Example of strlen command^J^M");

fdisplay("str value is : %s^J^Mlength of the string is

➥ %d^J^M", str, strlen(str));

display("Example of strcat command^J^M");

fdisplay("str value is : %s^J^M", str);

tail = " for strcat";

fdisplay("str value after concatenating with ‘%s’ is

➥ : ^J^M", tail);

strcat(str, tail);

fdisplay("%s^J^M^J^M", str);

display("Example of strcmp command^J^M");

str1 = "string";
