According to its type ''(see above)'', you can choose a value or method to be assigned to among a list of methods:

+

'''For Boolean variables:'''

Line 33: Line 34:

* prompt at execution time

* another boolean variable value

+

'''For Numeric variables (Integer or Decimal):'''

Line 39: Line 41:

* prompt at execution time

* mathematical expression that can include any existing numeric or boolean variable as well as any available numeric [[Magic text]] and some mathematical functions (list and syntax included)

+

* in addition, Integer type variables have 2 other kinds of settings: adding or subtracting 1 to current value (same as mathematical expression 'my_integer_variable +/- 1' but more convenient when incrementing/decrementing an index by step of 1)

+

in expressions, booleans have value 1 if true, 0 if false

+

and beyond usual arithmetic operators (+ - * /) you can use

+

:- ** for power

+

:- logical operators (&& for "and", || for "or") where the operands can be booleans or numbers (0 is false, any non-zero is true) and the boolean result is converted to number

+

:- comparisons between numbers (<= < == != > >=) where again the boolean result is converted to number

+

'''For String variables:'''

* fixed value (including concatenated string variables contents as well as any available [[Magic text]] or empty string to clear the variable content)

* prompt at execution time

+
