Free Variables

This is a list of System Variables that have no current function as of version 2.43.1g:

Memory locations between 50 and 175 are the traditionally used custom variables, and have been guaranteed not to be replaced with a sysvar in the future.

All other "free" System Variables memory address ranges (that may change to get a reserved purpose) are

• 13-17,
• 20-193, - the less likely to experience new sysvars, and so the "safest" place to put custom variables (start in the middle of this range and work outward)
• 222-299,
• 304-309,
• 316-329,
• 332-334,
• 342-399,
• 403-409,
• 430-436,
• 472,
• 488-500,
• 512-520,
• 540-684,
• 691-694,
• 700,
• 716-720,
• 732-799,
• 839-899,
• 902-919,
• 925-970,
• 971-976*, Epigenetic memory (5 addresses) that is instantly copied from a parent to all its children
• 976-990*, Epigenetic memory (15 addresses) that is copied trough the birth tie over time during 15 cycles, 976 first , 977 second...
• 991-1000
