Parsing Question

[Don Ewald]

Greetings!

I do appreciate the replies given and the suggestion by Mr. Hanlin is golden! I was heading down a path similar to the suggestion by Mr. Bertz; but, I figured that there had to be an easier method.

I can just imagine two different approaches to getting to the other side of a pole. My way, where I keep butting my head against the pole trying to get through because I know no better or someone pointing out that I can just walk around it.

Sometimes, in my programming, I feel the same. Many thanks, Tom!

Depends on what you need to parse, how. On the assumption that you're
just trying to pull the numbers from a sentence of this type, though, I'd
be inclined to keep it simple:

s$ = "You earn 58 experience points and find 43 gold pieces."
i% = instr(s$, any "0123456789")
xp& = val(mid$(s$, i%))
i% = instr(i% + len(str$(xp&)), s$, any "0123456789")
gp& = val(mid$(s$, i%))

I'm not sure the parse function is what you need - I don't believe
that there is a parse$ function in PBDOS.

In PBCC or PBDLL you could parse it like this

xp& = VAL(PARSE$(linetext$, ANY " ", 3))

Using the spaces between the words as delimiters

However, to accomplish the same thing in PBDOS you could
use mid$ to strip just the numbers out of the sentence with MID$.
(that is as long as the sentence was the same every time)

xp& = val(MID$(linetext$,10,3))

Greetings!

I'm having a few problems with parsing. I've a handful of lines similar to this one:

"You earn 58 experience points and find 43 gold pieces."

...that I'm attempting to parse. I'd like to end with two variables after parsing this line:

XP&=58
GP&=43

What's the easiest way to pull a variable number from this set sentence?
