Problem:

When calling / running an assembler module, the following error is displayed in the console.log :-

Execution error : file 'MF370UT0'
error code: 197, pc=0, call=1, seg=0
197     Screen handling system initialization error.

Resolution:

This problem is caused by the assembler program being compiled with the ANIM option set, but the animator cannot be loaded.

To animate an assembler program, set the environment variable ES_SERVER_CONSOLE=Y in the ES-Environment section of the region to be debugged.

If animate is not required, remove the error by recompiling the assembler program with the NOANIM directive set.
