Copy the macro module GTM$DEFAULTS.MAR from GTM$DIST.

              $ Copy GTM$DIST:GTM$DEFAULTS.M64 []
            

Edit 'GTM$DEFAULTS.M64 to modify the parameters controlling the desired factors.

              $ Edit GTM$DEFAULTS.M64
            

Example:

        GTM$DEFAULTS
        GTM$USER_STACK_SIZE == 16384
        GTM$USER_INDRCACHE_SIZE == 128
        GTM$USER_STRPL_SIZE == 20480
        GTM$USER_IO_TIMER == 3300000
        GTM$USER_WRITE_FILTER == 0
        GTM$SPECIAL_INPUT == ^X00200000
        GTM$UNDEF_INHIBIT == 0
        GTM$CTRLC_ENABLE == 1
        GTM$BREAK_MESSAGE_MASK == 15
        GTM$LOWER_CASE_LABELS == 1
        GTM$LVNULLSUBS == 1
        GTM$ZDIR$FORM == 0
        GTM$ZDATE$FORM == 0
            

This enables the alternative handling of (SPECIAL_INPUT) <CTRL-U>.

	GTM$DEFAULTS must have values for all parameters and all parameter names must be spelled correctly.
