*dump*
As you may have noticed, new mIRC 6.32 brought about some alternation (extension) to these limits:
12.Standardized and extended string lengths throughout mIRC to allow the use of longer variables, channel and nick names, and other items.
FYI (and mine, of course) here are some of the *new* limits, according to my tests:
max hash len (tablename + item + data):
v6.31: 939 -
v6.32: 4140
max var len (varname(including the % char) + data):
v6.31: 942 -
v6.32: 4143
max line len (echo):
v6.31: 942 -
v6.32: 4143
max window name len (including @):
v6.31: 90 -
v6.32: 256
