I'm probably going to explain this incorrectly, but the jist of the problem is
the literal periods in the PARSE statement.
Due to the literal periods ("."), PARSE assigns the values of "word1" and
"word2" to var1 and var2 respectively.
Then, PARSE assigns nulls to var3, var4 and var5 bringing the parse pattern and
variable's value into sync with the first literal period (".") and PARSE then
assigns "word3 word4:word5" to var6.
Finally, var7 is assigned "word6" and the trailing period is "assigned" the
remainder, "word7 hh.mm.ss".
Is this what you concluded?

Subject: Friday fun with REXX and PARSE
This is some Friday fun with parsing with REXX. First I was baffled with the
result, now I understand. So *no* I will not join the TSO/REXX list ;-)
I've got a data set to process with REXX. The records are of format:
"word1 word2.word3 word4:word5.word6 word7 hh.mm.ss"
What I need is each record split into:
var1 = "word1"
var2 = "word2.word3"
var3 = "word4:word5.word6"
var4 = "word7"
var5 = "hh"
var6 = "mm"
var7 = "ss"
Easy, I thought and coded:
PARSE VAR input var1 var2 var3 var4 var5 "." var6 "." var7 .
The result baffled me and was far from anything I understood at first. Here is
what the variables look like:
var1 ==> "word1"
var2 ==> "word2"
var3 ==> ""
var4 ==> ""
var5 ==> ""
var6 ==> "word3 word4:word5"
var7 ==> "word6"
Have fun.
