substring$ = LGETSTR$(longstringarray%(), start_position, number_of_chars)

test_string_position = LINSTR(longstringarray%(), test_string$ [,start_position])
string_comparision = LCOMPARE(first_longstringarray%(), second_longstringarray%())


r = LCompare( str1, str2 )
Compare the contents of two long string variables.
The returned value 'r' is an integer and will be -1 if 'str1' is less than 'str2'. It will be zero if they are
equal in length and content and +1 if 'str1' is greater than 'str2'. The comparison uses the ASCII
character set and is case sensitive. 'str1' and 'str2' must be long string variables.


r = LLen( str )
Will return the length of the string stored in the long string variable 'str'.

r = LInstr(str, srch, start )
Return the position of a substring in a long string.
The returned value ('r') is an integer and will be zero if the substring cannot be found. 'str' is the
string to be searched and must be a long string variable. 'str' is the substring to look for and it must
be a normal MMBasic string or expression (not a long string). The search is case sensitive.
Normally the search will start at the first character in 'str' but the second version allows the start
position of the search to be specifies as the number 'start'. In both the returned value ('r') and the
start position ('start') the first character in the string is number one.
For example, if the string str held "Hello world hello and hello":
PRINT LInstr(str, "worxx") Would print 0
PRINT LInstr(str, "Hello") Would print 1
PRINT LInstr(str, "hello") Would print 13
PRINT LInstr(14, str, "hello") Would print 23

s$ = LGetStr$( src, start, len )
Returns part of a long string as a normal MMBasic string.
's$' is the MMBasic string returned by the function. 'src' is the source long string variable, 'start' is
the character number in 'src' to start copying from (the first character is numbered one) and 'len' is
the maximum number of characters to return. If there are no characters to return 's$' will be an
empty string and if there are fewer characters than that 'len' then only they will be copied.
The following is an example of how to output a long string to a serial port using this function:
FOR i = 1 TO LLen(Str1()) STEP 250
PRINT #4, LGetStr$(Str1(), i, 250);
NEXT i

TRANSMIT HTML

Used to construct and transmit an HTTP 1.1 header of the required length
that contains all buffered PRINT outputs to the fileno opened with
OPEN "SOCKET" as #fileno

OPEN "SOCKET [interrupt][,count]" as #n

...change TRANSMIT to TRANSMIT HTML

PWM pin, STOP

Stops PWM output on the 'pin'


SERVO pin, STOP

Stops output to the 'pin'

FIELD$(datastring$,fieldno,delimiter$)

returns a field from the datastring$
delimiter$ is the delimiter, defaults to "," if not entered.
fieldno is the required field position to be extracted.Returns "" if field requested is bigger than number of fields.

MM.ONEWIRE

The system variable MM.ONEWIRE is maintainted to show status of OWSEARCH as for ONEWIRE communication
(1=success, 0=failure/no result) See MM manual for other ONEWIRE details.


OWSEARCH (pin, flag [,serial_number_mask)
Flags are:
0 - Continue an existing search
1 - start a new search
4 - Continue an existing search for devices in the requested family
5 - start a new search for devices in the requested family (the MSB of the serial_number_mask)
8 - skip the current device family and return the next device
16 - verify that the device with the serial number in serial_number_mask is available
The system variable MM.ONEWIRE is maintainted as expected (1=success, 0=failure/no result)

IR

As for MM but IR receive pin is 33.

SETPIN pin [CIN|FIN|PIN]

Only pins 12,24,29 and 33 allowed for CIN,FIN,PIN config options.
AIN option is not supported. See ADC function for analogue input.
All other SETPIN options as per MM

FORK unix_command

.......
Note that the unix command does not need quotes or specific field separators but
commas may be used instead of spaces if preferred.
Note also that the C-library parser does not accept "-" characters in filenames
as these are treated as specific to command syntax.
