Hi,
With this code :
#!/usr/local/bin/hbrun
proc main()
? 1234567890123456789
? 12345678901234567890
return
i get these results (linux debian):
1234567890123456789
12345678901234570000
strange no ?

Sorry, with or without ? I got inverse
I get:
With HB_LONG_LONG_OFF:
( set C_USR=-DHB_LONG_LONG_OFF )
[E:\harbour801\bin]hbrun.exe test.prg
1234567890123457000
Without HB_LONG_LONG_OFF:
( Rem set C_USR=-DHB_LONG_LONG_OFF )
[E:\harbour801\bin]hbrun.exe test.prg
1234567890123456789
