  COBOL-related (DCOB$) Link Errors? 
 The Question is:
 
We are converting COBOL programs from VAX OpenVMS 6.2 to ALPHA OpenVMS Version
 7.2-1.
The following is happening and the program is crashing when it executes.  We
 are getting the following LINKing situation:
ALPHA2 &gt; cob ub-884
ALPHA2 &gt; link ub-884
%LINK-W-NUDFSYMS, 4 undefined symbols:
%LINK-I-UDFSYM,         DCOB$CVT_I4_Q
%LINK-I-UDFSYM,         DCOB$CVT_Q_I4
%LINK-I-UDFSYM,         DCOB$EXPI4
%LINK-I-UDFSYM,         DCOB$ROUNDI4
%LINK-W-USEUNDEF, undefined symbol DCOB$ROUNDI4 referenced
        in psect $LINK$ offset %X000009A0
        in module UB_884 file DEV_UB:[TEST]UB-884.OBJ;15
%LINK-W-USEUNDEF, undefined symbol DCOB$EXPI4 referenced
        in psect $LINK$ offset %X00000F60
        in module UB_884 file DEV_UB:[TEST]UB-884.OBJ;15
%LINK-W-USEUNDEF, undefined symbol DCOB$CVT_I4_Q referenced
        in psect $LINK$ offset %X00000F70
        in module UB_884 file DEV_UB:[TEST]UB-884.OBJ;15
%LINK-W-USEUNDEF, undefined symbol DCOB$CVT_Q_I4 referenced
        in psect $LINK$ offset %X00000F80
        in module UB_884 file DEV_UB:[TEST]UB-884.OBJ;15
And it is constantly crashing with the following in the program:
 
W-MAX-VOLUME-THIS-METER-PLUS-100000000
%COB-F-CALL_FAILED, call failed to find program
%TRACE-F-TRACEBACK, symbolic stack dump follows

 The Answer is:
 
:ALPHA2$ link ub-884
:%LINK-W-NUDFSYMS, 4 undefined symbols:
:%LINK-I-UDFSYM,         DCOB$CVT_I4_Q
:%LINK-I-UDFSYM,         DCOB$CVT_Q_I4
:%LINK-I-UDFSYM,         DCOB$EXPI4
:%LINK-I-UDFSYM,         DCOB$ROUNDI4
 
    You need to install the V2.6 or V2.7 COBOL RTL as detailed in the
    COBOL release notes.  It appears you have installed the V2.6 or V2.7
    COBOL compiler, but you have not installed the V2.6 or V2.7 COBOL
    RTL.
 
    The V2.7 COBOL RTL is shipping today both with OpenVMS Alpha V7.3
    and on the layered product CD-ROM.  The V2.7 COBOL RTL can be
    installed on OpenVMS Alpha V6.2 and higher.
