Seems you are right. It is actually only documented in the manual page
for stapvars (5). BTW. the language reference manual should also be
installed locally, probably somewhere as:
/usr/share/doc/systemtap-0.8/langref.pdf
(but indeed, the new argv/argc support isn't in there, sorry)

There is strtol:long (str:string, base:long)
That one is documented in the language reference (9.9 String Functions)
