Unlike XC8’s const , C18 uses rom to place constants in program memory.
After a 60-day trial period, the advanced optimization flags are disabled. The compiler still functions perfectly and compiles valid code, but the output file size can increase by 30% to 50%, which may cause "Memory Overflow" errors on smaller chips. mplab c18 347 full version best
