Maximum length of toolpalette command strings

[Mark.HarrisBGNSX]

Hi all, can someone please tell me the max length of a toolpalette command string?  I just tried adding in all the variables I want and it seems to be too long, so would be useful knowing how many characters I have to play with

Thanks,

Mark
