SPLIT "10,11,12" by "," to sub1, sub2, sub3, sub4 yields

sub1 = 10

sub2 = 11

sub3 = 12

(sub4 is undefined)

If there are fewer variables than sub-strings, the last string variable will hold the remaining part of the origi-

nal string and the delimiter. Example,

SPLIT "10,11,12" by "," to sub1, sub2 yields

sub1 = 10

sub2 = 11, 12

If two delimiters follow each other, the resulting variable is empty. Example:

SPLIT "10, ,11" by "," to sub1, sub2, sub3 yields

sub1 = 10

sub3 = 11

(sub2 is empty)

All variables are considered strings when they are split. You need to convert those string values into real val-

ues using the VAL function if you want to compare them as numbers. If the values are not converted, they

are compared as strings and the string "17.32" is evaluated as greater than "115.22." Example:

temp_string = "17.32,115.22"

SPLIT temp_string by "," to a,b

real_value_of_a = VAL(a)

real_value_of_b = VAL(b)

if real_value_of_a > real_value_of_b then

greatest = a

else

greatest = b

end if

SPLITA

The syntax of this function is

SPLITA string by delimiter to array_variable

This function splits "string" into array elements in "array_variable" separated by "delimiter." Delimiters at

the beginning or end of the expression are ignored. Example:

SPLIT "10, 11, 12" by "," to var_array yields

var_array[0] = 10

var_array[1] = 11

var_array[3] = 12

If two delimiters follow each other, the resulting array element is empty.Example,

SPLITA "10, ,11" by "," to var_array yields

var_array[0] = 10

var_array[1] =

var_array[3] = 11

(the second array element is empty)

SQR

This function returns the square root of the argument. If the argument is undef, the result is undef. Example:

y = SQR(9.0) yields y = 3
