Intrinsic Error Messages
27
Cause. A PARAM specifies a value that is ambiguous in the current context. For 
example, the PARAM specification:
PARAM PRINTER-CONTROL A
is ambiguous if the program contains more than one logical file named A.
Effect. The run-time terminates the program.
Recovery. Correct the PARAM in your TACL environment. For more information on 
using PARAMs, see the TACL Reference Manual.
28
Cause. The run-time library for a module that is written in language is not available 
to the program.
Effect. The run-time terminates the program.
Recovery. Consult your system administrator.
29
Cause. The language compiler used features that are not supported by the language 
run-time library that the program used.
Effect. The run-time terminates the program.
Recovery. Use a compiler and run-time library that are compatible. You might need to 
consult your system administrator.

Run-time libraries report the messages in this subsection if an error is detected in a 
math function.
40
Cause. A function detected a problem with its parameters.
