Updated 2026-09-09 · LogrobotLM reference

Cause

It is not a simple variable that is correctly described by its name alone, or it is a variable used in an incorrect context. Instead of the name of a simple variable, the name of a subprogram, for example, has been used, or it is an array variable that has been used without an index. Example 1: DEF hhh() hhh=1 END Example 2: INT Hugo[3] Hugo=1

Effect

The program is not executable.

Troubleshooting

Modify the program.
