Warning: These values may be outdated for mIRC v6.32. Updated and confirmed sections are marked with (Updated)
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, includes spaces.)
Credit for this information goes to Saturn unless otherwise specified.
You can find the original limits page here.
|Global limits (Updated)|
|Line Length Limit|
|4150||Truncated or error||To be precise: 4150 for evaluation results, 4151 for command lines (excluding command prefixes.)|
(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) [Credit: Daveoh]
