procedure memset(p : ^byte; character : byte; n : word);

The function fills the first n words in the memory area starting at the address p
with the value of word 

character

.

For parameter p you can use either a numerical value (literal/variable/constant)
indicating memory address or a dereferenced value of an object, for example

@mystring or @PORTB

.

procedure strcat(var s1, s2 : string[100]);

The function appends the value of string s2 to string s1 and terminates s1 with a
null character.

function strchr(var s : string[100]; ch : byte) : word;

The function searches the string s for the first occurrence of the character ch.
The null character terminating s is not included in the search.

The function returns the position (index) of the first character ch found in s; if no
matching character was found, the function returns 

0xFFFF

.

function strcmp(var s1, s2 : string[100]) : short;

The function lexicographically compares the contents of the strings s1 and s2
and returns a value indicating their relationship:

Value    Meaning
< 0      s1 "less than" s2

= 0      s1 "equal to" s2
> 0      s1 "greater than" s2

The value returned by the function is determined by the difference between the
values of the first pair of words that differ in the strings being compared.
