问个Allegro对文件名的问题！

Allegro对文件名长度和命名有啥要求啊？

$ |7 E* R# q, i6 q% _/ E% |我只知道PAD的文件名长度是18个字符。
# |- c4 u; S3 h- p6 ^) \0 c2 P2 c- dSYMBOL呢？
' a  J  F$ i& O* y  t- P) v5 G2 UBRD呢？

: {+ _( L) [6 D" t4 j8 GORCAD Caputre对文件名长度和命名有啥要求吗？
0 {0 l5 Q. d! M+ B3 Y8 O7 y5 X" K
% P$ {5 G, p% ]' M8 \- j0 f# Z有大虾知道么？

Allegro中不要有中文和一些特殊字符,一般用字母,数字为好, 好象有相关的贴讲过的, 具体你搜一下.

找了好些地方也没找到，那位能指导一下吗？

没人理我，只有自己找吧，好累！

Unless otherwise indicated, the layout editor only supports uppercase characters. If you enter lowercase characters, the tool converts them to uppercase. Printable characters are generally any key on a standard keyboard with the exception of Tab, Backspace, Enter, function keys, Esc, and navigation keys (Arrows, Home, and so on.).

1 Allows lower case for general text unless on a special layer where it may adhere to more restrictive rules; for example, many layers show Refdes.

2 File names adhere to operating systems restrictions except if they are stored in the database, where they assume the least common denominator. For example, a .psm file becomes a package symbol in the database so its least common denominator is the package name restriction. Spaces in the name are not supported. It is strongly suggested that you use lower case, especially for those names stored in the tool database.

* h+ ?  J6 _0 `8 b" s, h3 Directory names follow operating system limitations. The layout editor supports spaces in directory names on Windows.

4 The default maximum number of characters is 31. You can set the initial length for new designs to a maximum length of 255 by using the allegro_long_name_size environment variable (choose Setup - User Preferences (enved command)). You can change the size in existing designs by choosing Setup - Design Parameters (prmed command) and specifying a new maximum for the Long Name Size parameter in the Design tab.

Note: For releases prior to 16.0, the environment variable allegro_long_package_name is only used as part of the uprev process to override the design's default name length limit.
