String represents a sequence of characters. String type is similar to array, but can

hold only characters.

dim M_name as string[16]

dim Start_message as string[6]

For each string declaration, compiler will reserve the appropriate amount of mem-

ory locations. For example, string M_name will take 16+1 locations; additional

memory location is reserved to contain the length of the string. If we assign string

literal to variable M_name,

M_name = "mik", then:

M_name[0] will be 3 (contains length of the string)

M_name[1] will be 'm'

M_name[2] will be 'i'

M_name[3] will be 'k'

and all other locations will be undefined.

Assignment operator can be used with string variables:

dim M as string[20]

S as string[8]

main:

M = "port"

' Assign 'port' to M

S = "port1"

' Assign 'port1' to S

end.

mikroBasic includes a built-in function Length for working with strings:

sub function Length(dim text as string) as byte

It returns string length as byte, and is quite useful for handling characters within

string:

M = "mikroElektronika"

for i = 1 to Length(M)

Lcd_Chr(PORTD,1,i,M[i])

next i
