Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

THE VALUE IS NOT VALID FOR THE RESERVED
VARIABLE.
 
Word sets aside certain variable names as
"reserved variables" with specified values. You
attempted to set a reserved variable to an
incorrect value. For example, the instruction
«SET echo="yes"» is not valid. The reserved
variable, echo, can only be set to "on" or "off."
 
■ Edit the macro to correct the value for the
  reserved variable. For example,
  «SET echo="on"» is valid.
■ For a list of acceptable values for reserved
  variables, see Ch. 22, "Macros," in the
  Using Manual.
