.ERRB            Error If String Is Blank                      MASM Directive

.ERRB     <string>

Forces a fatal error if string is blank.

Notes:     Note that the angle brackets, <>, are required around
the string.  The string can be any name, number, or
expression.

The error message that may be generated by this
directive is 'Forced error - string blank', which is
error number 94.

If an error is generated, then the object module is
deleted and the assembler exits with an exit code of 7.

.ERRB and .ERRNB are usually used to detect the presence
or absence of parameters in a macro.
