Informix Error -16377

-16377 Cannot retrieve values of global variables before execution begins.

A PRINT command cannot display the value of a global program variable until after execution begins. Invoke the RUN or CALL command to begin execution and then repeat the PRINT command. In this situation, you can specify constants or the names of global variables as arguments of CALL. (You might have to set a breakpoint or press the Interrupt key to suspend the program before normal termination.)

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-16377 fires when PRINT targets a global variable before execution has begun — per the official guidance.

  1. PRINT on a global variable before RUN/CALL has started execution, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Invoke RUN or CALL to begin execution, then repeat PRINT, per the official guidance.
  2. In this situation, CALL arguments can use constants or global variable names, per the official guidance.
  3. Set a breakpoint, or press Interrupt, to suspend the program before normal termination, per the official guidance, if needed to keep it running.
