 A Bacon programming question.

Hi,
How do I input three floating point numbers without hitting the enter key three times?
Is BaCon the right language to use for simple floating point maths?
Regards Tony.

Make a GUI and use the mouse thus you don´t have to hit the enter key. Or separate them by a space, hit the enter key once and use the words.....
simplest tool for floating point math is /usr/bin/bc
ex: | Code: | # echo "3.14*2" | bc -l
6.28

Hi L18L,
thank you for coming back. Here is my simple Bacon program :-
DECLARE prot,carbs,fat,points TYPE float
INPUT "protein ",prot
INPUT "carbohydrates ",carbs
INPUT "fat ",fat
points = prot/10.94 + carbs/9.17 + fat/3.89
PRINT "points: ",points
I would like to replace the three input statements by a single one liner.
Obviously inputting floating point numbers into say a three by three, or an even larger matrix would be a bit tedious.
My apologies for not being very clear in my first post
Regards Tony.

Hi Tony,
try this:
DECLARE prot,carbs,fat,points TYPE float
'INPUT "protein ",prot
'INPUT "carbohydrates ",carbs
'INPUT "fat ",fat
INPUT "protein carb fat: ", pcf$
SPLIT pcf$ BY " " TO c$ SIZE num
prot = VAL(c$[0])
carbs = VAL(c$[1])
fat = VAL(c$[2])
points = prot/10.94 + carbs/9.17 + fat/3.89
PRINT "points: ",points
