Macros:
Simple macros for typing commonly used commands and other
texts are defined by system parameters M1,M2,...,M9.
Macros are defined in the SURVO.APU file as lines of the form
M#=<macro_text>.

Each macro is activated by pressing the F2:PREFIX key and then # of
the macro. Macros of this type are for typing of text only. No special
characters are allowed.

Key sucros offer much more general possibilities (see SUCROS?) 

Examples: M1=SCRATCH
          M7=3.141592653589793 .
`!' at the end of macro means activating it as a command.
