         only available if FailAt is set to greater than 10.
FAIL   - True if previous return code is greater than or equal to 20;
         only available if FailAt is set to greater than 20.
EQ     - a EQ b: true if the text of a is equal to the text of b
         (disregarding case).
GT     - a GT b: true if the text of a is greater than the text of b

         the text of b (disregarding case).
         Use NOT GE for less than or equal to.
VAL    - a VAL b: true if the text of a and b is identical (disregarding case).

NOTES: if more than one of the three condition-flag
       keywords (WARN, ERROR, FAIL) are given, the one
       with the lowest value is used.

       You can use local or global variables with If by
       prefacing the variable name with a $ character.

Example:

If EXISTS Work/Prog
    Type Work/Prog HEX
Else
    Echo "It's not here"
EndIf
