Re: Bug with periods in [math] variable names

texte = >IMHO it is rather lame to develop software that cannot adhere to a few simpleAlways a pleasure to read your messages, KG.>1- Math variable names have limited string lengths, while no other variables have this limitation.The math routines are based on a publicly-distributed library which has these limitations built in. We extended the length of variable names per user requests, but could not get around the fact that they are fixed-length. Someone would have complained even if we limited them to 255 chars, so we set a reasonable length, and moved on to more important things.>2- Math variable names cannot include anything except alphabetical characters or numeric digits, but no other variables have this limitation.As any programming language will do: the ambiguity introduced when you start putting math operator characters in the middle of variable names makes it very difficult to parse equations correctly.x*y*z := multiply variable x times variable y times variable z x*y*z != multiply variable named x*y times variable z>3- Math variable names cannot begin with a numeric digit, yet no other variables have this limitation.x*7 := multiply variable x times the number 7 x*7y :: is it x*7 followed by y, or is it x times variable 7y------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
