A trivial item, but this surprised me.
I wanted to parse out the string 'word3' using the period as a place holder.
The input could have a blank delimited string containing an embedded period
before the one I wanted to parse out. The Parse Var as coded didn't work.
Using the Parse Value as coded there does work. I didn't know it would behave
like that. I can't seem to find this documented but I might have overlooked
something.
myVar = 'word1 word2 9.12 word3.ext'
Parse Var myVar . . . myVal '.' .
Parse Value Subword(myVar,4) with myVal2 '.' .
Say 'myVal=' myVal
Say 'myVal2=' myVal2
Exit
Trace R of that code:
3 *-* myVar = 'word1 word2 9.12 word3.ext'
>>> "word1 word2 9.12 word3.ext"
4 *-* Parse Var myVar . . . myVal '.' .
>.> "word1" -
>.> "word2"
>.> "9"
>>> ""
>.> "12 word3.ext"
5 *-* Parse Value Subword(myVar,4) with myVal2 '.' .
>>> "word3.ext"
>>> "word3"
>.> "ext"
6 *-* Say 'myVal=' myVal
>>> "myVal= "
myVal=
7 *-* Say 'myVal2=' myVal2
>>> "myVal2= word3"
myVal2= word3
8 *-* Exit
