I'm trying to extract the first number after a hyphen. For example,
from x="1234-1" I want to create y=1.
gen y = regexs(1) if regexm(x,".*-([0-9]+)")
will work if the number after the hyphen is always a positive
integer. The same approach can be easily modified to accommodate
negative and/or decimal numbers (i.e., by modifying the regular
expression).
