syncdraw lost @-codes on file load

Syncdraw won't load the @-CODES from .msg file

steps to reproduce:

• open syncdraw
• put some @code like @SEC@
• save as "sync" with "test.msg" as filname
• close syncdraw

• load the file again:
• ./syncdraw test.msg

the @SEC@ code do not show

expected result: the file must have @SEC@ code
