The switch OPTIONS=NOSPACEATTR eliminates the automatic space associated with the on/off field attributes (TCRT commands 21,22,30-35,100-105). Currently this only applies to the AM75{G} UNIX emulation, and was implemented to provide compatibility with applications developed with a very old AMOS terminal driver standard in which mode emulation drivers did not automatically add the space which otherwise was added by field terminals directly. Note that if OPTIONS=NOSPACEATTR on the server side, the option will be automatically forwarded to ATE.
