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 (Updated) | |||
| 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 9144 due to the 4 characters used by "set ". (LLL) |
