Survo system parameters are changed permanently by SYS command.
SYS <word>=<value> 
sets a new line <word>=<value> in the SURVO.APU file. If the <word> 
line already exists, it's value is replaced by the new one.
SYSDEL <word> 
deletes the <word>=<value> line from SURVO.APU.
After SYS and SYSDEL the new contents of SURVO.APU is valid
when Survo is started again or a SETUP SURVO.APU command is given.

For temporary changes (valid in the current Survo session only) the
SYSTEM command should be used.
