List of expression elements / Assignment operators |
The := operator assigns a variable with an expression and returns the result.
variable := expr
The := assignment operator puts a value in the left-hand variable and the resulting value can again be used in an expression.
Do not confuse with the LET instruction.
The := assignment operator has the lowest precedence, it can be used at many places and can simplify coding.
In the next example, the := operator is used to increment the array index before usage:
MAIN DEFINE arr DYNAMIC ARRAY OF STRING, idx INTEGER LET idx = 0 LET arr[idx:=idx+1] = "One" LET arr[idx:=idx+1] = "Two" LET arr[idx:=idx+1] = "Three" END MAIN
