TACL Error Messages
Cause. The CPRULES file version is no longer supported by this RVU of TACL.
Effect. The requested operation is ignored.
Recovery. See your service provider to obtain a new copy of the CPRULES file in
question.
Cause. You referred to a nonexistent variable. (This problem also occurs if you embed
a dollar sign in a text argument that is terminated by a dollar sign.)
Effect. The requested operation is ignored.
Recovery. Check the spelling of the variable reference; if it is correct, ensure that you
define the variable before referring to it. (Check to see if the argument can be bounded
by alternative delimiters.)
Cause. You referred to a nonexistent level of an existing variable.
Effect. The requested operation is ignored.
Recovery. Check the level specification, and check your method of creating levels for
the variable, to ensure that they correspond.
Cause. You attempted to push, pop, change the value of, or set a breakpoint on a
variable in a shared segment. The contents of shared segments cannot be changed.
(Setting a breakpoint forces TACL to turn on a flag in the variable, thus changing it.)
Effect. The requested operation is ignored.
Recovery. First detach the segment, then reattach it in the private mode before
attempting to change any variables in it. Return the segment to the shared mode
afterward.
Cause. A numeric variable is required.
Effect. The requested operation is ignored.
Recovery. Correct the indicated variable. A numeric variable can contain nothing
other than a single decimal number, optionally preceded or followed by spaces and
blank lines.
*ERROR* Variable does not exist
*ERROR* Variable does not have that level
*ERROR* Variable is in a shared segment making it read-only
*ERROR* Variable is not numeric
