Why do we need Functions?

[mnrvovrfc]

If you want to complicate your life further but absolutely hate the type sigils, especially for a string "function" then a "SUB" with "side-effects" could work. Have to declare variables "AS STRING" to keep avoiding that dollar sign...

Code: (Select All)

''Example:

DIM SA AS STRING
SA = ""
PRINT SA
CALLME "Hello!", SA
PRINT SA
END

SUB CALLME (SVAL AS STRING, SINP AS STRING)
  SINP = SVAL
END SUB

''as opposed to:

DIM SA AS STRING
SA = ""
PRINT SA
SA = CALLME$("Hello!")
PRINT SA
END


FUNCTION CALLME$ (SVAL AS STRING)
  CALLME$ = SVAL
END FUNCTION

I like to put "SUB" parameters at the end, those that will have the "side-effects".
