Run-Time Messages
Even if your program compiles and links with no errors, you may encounter
one of the following error messages when you try to run the program.
68 MESSAGE **** Data memory protection trap (TRAPS 68)
CAUSE A misaligned parameter was passed to a subprogram that
expects a parameter that is aligned on a 32-bit (16-bit)
boundary.
ACTION Relink with the PARMCHECK value set to 3 (the default). An
error message should appear for each call that passes a
misaligned parameter. See the "Link Editor Message"
(earlier in this chapter) change calls to subprograms that
have misaligned parameters.
---------------------------------------------------------------------------------------
57 MESSAGE **** Instruction memory protection (TRAPS 57)
CAUSE Issuing an illegal GO TO statement or exiting at a common
point from multiple PERFORM statements caused this error. A
GO TO statement is illegal if it is used to leave a
paragraph that was PERFORMed without returning to that
paragraph.
ACTION Use the $CONTROL BOUNDS option when compiling the program to
detect this error.
---------------------------------------------------------------------------------------
512 MESSAGE UNRESOLVED EXTERNALS: <external name> (LDRERR 512)
CAUSE
a. CALLing COBOLLOCK or COBOLUNLOCK; or
b. CALLing a subprogram with a name that does not match the
subprogram's name because embedded hyphens are no longer
removed, the names are downshifted, or because COBOL
II/XL recognizes the first 30 characters of external
names; or
c. CALLing an intrinsic without using the keyword
INTRINSIC.
ACTION
a. Change COBOLLOCK and COBOLUNLOCK calls to EXCLUSIVE and
UN-EXCLUSIVE statements, respectively.
b. Change the main program or the subprogram names to
match.
c. Change the call to an intrinsic to explicitly use the
keyword INTRINSIC or use $CONTROL CALLINTRINSIC.
