It's very good to read the words 'I'm new to VMS'. Hopefully you enjoy the ride! -----Original Message----- From: "Pinoccio" <pinoccio at gmx.com> Sender: owner-hecnet at Update.UU.SE Date: Sun, 27 Nov 2011 21:34:04 To: <hecnet at Update.UU.SE> Reply-To: hecnet at Update.UU.SESubject: RE: [HECnet] Linker warnings Thank you! I am new to VMS so some of its useful facilities (as HELP /MESSAGE) not yet known to me. -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Peter Coghlan Sent: Sunday, November 27, 2011 9:17 PM To: hecnet at Update.UU.SE Subject: Re: [HECnet] Linker warnings Can anyone bring some light on these linker warnings: %LINK-W-TRUNC, truncation error in psect CODE offset %X0000046C in module XXX file YYY -LINK-W-TRUNCDAT, computed value is %X00000080 value written is %XFFFFFF80 at location %X0000A2B8 Assuming this is VMS, $ HELP /MESSAGE says: TRUNCDAT, computed value is 'value1' value written is 'value2' at location 'address' Facility: LINK, Linker Utility Explanation: Usually, this error occurs when a reference using byte or word PC-relative displacement is made to a target requiring longword relative displacement. 'Value1' is the value the linker needed to store; 'value2' is the value the linker is able to store (a truncated version). User Action: Correct the reference to use longword relative addressing mode. For something more specific, it would help to know more background. Regards, Peter Coghlan.
