Submitted-by: routley@tle.ENET.DEC.COM (Kevin Routley)
Posting-number: Volume 11, Issue 84
Archive-name: larn/Part01
Environment: Unix, VMS, MS-DOS, termcap
[This is the source for Larn V12.2, an enhancement of the
original Larn (written by Noah Morgan) by Kevin Routley.
This version is different than Ularn which was previously
posted in volume 7 and is closer to the original in
"look and feel". It is known to compile on Unix, VMS and
MS-DOS. PC executables were previously posted to
comp.binaries.ibm.pc. -br]

# This is a shell archive. Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file". To overwrite existing

XAs promised, here is the source to Larn V12.2, the executables for which were
Xposted earlier this year to comp.binaries.ibm.pc.
X
XThe source correctly compiles and executes under DEC Ultrix, using the cc
Xcompiler. The enclosed Makefile is for U*ix systems.
X
XThe source correctly compiles and executes under VAX/VMS, using the VAX C V3.x
Xcompiler. The enclosed descrip.mms is a MMS file for building under VAX/VMS.
X
XThe source correctly compiles and executes under MS-DOS, using Turbo C V2.0 or
XTurbo C++ V1.0. The LARN.PRJ file is for Turbo C V2.0, but unfortunately I am
Xunable to properly distribute the Turbo C++ project file and setup files. To
Xcompiler under MS-DOS, you must define the MSDOS, DGK, SYSV, DGK_MSDOS and
XNOVARARGS defines.
X
XI am interested in receiving source changes that allow Larn to be ported to
Xother architectures or operating systems. I am also interested in constructive
Xchanges or additions to improve the game. I am _not_ interested in arbitrary
Xmods, a la UltraLarn.
X
XBug fixes, bug reports, and requests welcome.
X
XI am reachable at tle.enet.dec.com!routley or routley@tle.enet.dec.com.
XBecause I am right in the middle of moving at the moment, all USmail should be
Xsent to:
X
XKevin Routley
XDigital Equipment Corporation
XZKO2-3/N30
X110 Spitbrook Road
XNashua, NH 03060
X
Xinstead of the address listed in the documentation file.
