[RBASE-L] - SLEN(...) - To Dot or Not?

[J. Stephen Wills]

Does it make any difference when I use SLEN(...) whether or not I dot the variable being passed?   At the command line, I tested this as follows :   R>SET VAR vMyVariable TEXT="I am 6"   R>SELECT SLEN(vMyVariable),SLEN(.vMyVariable) FROM MY_SMALL_DUMMY  SLEN (vMyV SLEN (.vMy  ---------- ----------           6          6   So, the results are the equal.  But is either approach in-correct or subject to inappropriate results?  It seems that I've encountered, at least once, some sort of what-seemed-to-me anomalous behavior.  Maybe using a dotted var on the left side of flow-control (IF-THEN, WHILE-THEN, ...) comparison?   Anyway, appreciate any enlightenment, as I'm trying to track down a whole in some code I'm modifying and I want to definitively move this issue from the UNKNOWNs to the KNOWNs.   TIA, Steve in Memphis
