sub function strcspn(dim byref s1, s2 as string) as word
Description The function searches the string s1 for any of the characters in the string s2.
The function returns the index of the rst character located in s1 that matches any character in s2. If
the rst character in s1 matches a character in s2, a value of 0 is returned. If there are no matching
characters in s1, the length of the string is returned (not including the terminating null character).
Example
txt = “mikroElektronika”
txt_sub = “mikr”
res = strcspn(txt_sub,txt)
Prototype
sub function strpbrk(dim byref s1, s2 as string) as word
Description The function searches s1 for the rst occurrence of any character from the string s2. The null
terminator is not included in the search. The function returns an index of the matching character in s1.
If s1 contains no characters from s2, the function returns 0xFFFF.
Example
txt = “mikroElektronika”
txt_sub = “mikr”
res = strpbrk(txt_sub,txt)
Prototype
sub function strrchr(dim byref s as string, dim ch as byte) as word
Description The function searches the string s for the last occurrence of the character ch. The null character
terminating s is not included in the search. The function returns an index of the last ch found in s; if no
matching character was found, the function returns 0xFFFF.
Example
txt = “mikroElektronika”
res = strrchr(txt,”k”) ‘ returns the index of the ‘k’ character of the
‘txt’ string
Prototype
sub procedure ltrim(dim byref astring as string)
Description The procedure trims the leading spaces of the string.
Example
txt = “ mikroE”
ltrim(txt) ‘ trims the leading 2 spaces of the ‘txt’ string
