Limits
From Scriptwiki
Warning: Not all of these values are updated for mIRC v6.32 and above. Sections which remain to be confirmed are marked with (Untested)
This page explains various limits imposed by mIRC, however this may not be a complete list. The length is measured in bytes (equivalent to ASCII characters, including spaces.)
You can find the original limits page here.
mIRC
| Name | Length | When exceeded | Description |
| Global limits | |||
| Line Length Limit (LLL) | 4150 | Truncated or error | To be precise: 4150 for evaluation results, 4151 for command lines (excluding command prefixes.) |
| Variables (local or global) | 4150 | Unset | This limit includes the variable's name. Example: using "%a" as a name uses 3 bytes (2 for the name and 1 for a space.) This means that for every extra character in the variable name, the maximum length of the value is reduced. Note: the /set command further reduces the length limit to 4144 due to the 4 characters used by "set ". (LLL) |
| Calculations | Max value: 9007199254740992 | Inaccurate | Calculations past this number will generally be incorrect. Only the first 15 numbers of the result will be accurately calculated. |
