Ron,
I'm curious about what intention on application with these results:
str('a',10,2) -> ' 97.00'
strzero('b',10) -> '0000000098'
padl("9","*",10) -> 42 spaces + "9"
padr("9","*",10) -> "9" + 42 spaces
padc("9","*",10) -> 20 spaces + "9" + 21 spaces
IMO, this can cause damage on the expected results, mainly from Clipper legacy
applications.
I still think more prudent to separate this *feature* in HB_IS_NUMERIC_EXT and
use it only on specific issues.
Please, consider it.
Eduardo
