String Concatenation

Description

String concatenation is joining strings together.

Syntax

JB has two string concatenation operators:

stringExpression + stringExpression

the result is a string expression,

and

anyExpression ; anyExpression

anyExpression will be converted into a string and then the strings are concatenated,

the result is a string expression.

Hints

Experiments show that (;) operator has lowest possible priority, while (+) has priority above relational operators. So

"2">"3"+"1"

first performs string concatenation, then comparison, and result is <false> (numeric 0), while

"2">"3";"1"

first performs comparison, gets <false> (numeric 0), then converts it to string and concatenates. Result in this case is string "01".

Example

    varOne$ = "Hello"
    varTwo$ = "World"
    varThree$ = varOne$ + " " + varTwo$
    print varThree$

    varOne$ = "Hello"
    varTwo$ = "World"
    varThree$ = varOne$ ; " " ; varTwo$
    print varThree$

    varOne$ = "Apollo"
    varTwo = 17
    varThree$ = varOne$ ; " " ; varTwo
    print varThree$

    varOne = 19
    varTwo = 72
    varThree$ = varOne ; varTwo
    print varThree$
