Parse warnings are generated for conditions that may have unexpected results or indicate a
possible oversight in the Local Logic Program.

Assignment to binary variable may result in loss of data
This message is generated when a Boolean variable is assigned from a non-Boolean
variable or constant, or an expression containing non-Boolean variables.

This warning is generated for programs exceeding 100 statements. While there is a
maximum instruction limit of 150 statements, it is possible to write a Local Logic
program that takes too long to execute.
For instruction times, refer to appendix A in the PACSystems CPU Reference Manual,
GFK-2222 or Series 90-30 CPU Reference Manual, GFK-0467
