Basic Commands and Functions
The array will be automatically sized (larger or smaller) based on the number of strings that are
produced by the split. The number of strings produced will also be returned by the function.
var$ = “Analog1,Analog2,Analog3-Analog2,-Analog4”
ARRAY arr$(1)
result = SPLIT(var$, arr$(), “,-”) REM split on commas or dashes
FOR i = 1 TO result REM result = 6
REM prints “1:Analog1 2:Analog2 3:Analog3 4:Analog2 5: 6:Analog4”
PRINT i, “:”, arr$(i), “ “;
NEXT i
45
Returns the squared value of the given number. The caret (“^”) may also be used to raise a number
to a power, such as 2.
var = SQR(5) REM stores 25 in the var variable
PRINT 4^2 REM prints “16”
SQR (number)
Returns the square root value of the given number. The caret (“^”) may also be used to raise a
number to a power, such as 1/2.
var = SQRT(25) REM stores 5 in the var variable
PRINT 16^(1/2) REM prints “4”
SQRT (number)
Specifies an optional increment in a FOR loop. Positive or negative numbers may be used.
FOR a = 10 TO 1 STEP -2
PRINT “ “, a; REM prints “ 10 8 6 4 2”
NEXT a
STEP
Returns a string for the given number. An optional second parameter string may be specified to
declare the format to be used. Formats are specified using the hash character (“#”). If not enough
hashes are specified, the format will be returned.
var$ = STR$(18.265, “##.####”) REM stores “18.2650” in var$
var$ = STR$(18.265, “#######”) REM stores “ 18”
PRINT STR$(18.265) REM prints “18.265”
PRINT STR$(18.265, “#.#####”) REM prints “#.#####”
STR$ (number, string)
