| Maybe I should have included the example where it does the math
| correctly within  MIN().  The following code:
| 
|        Then:  A(3,.0)="25"
|        Then:  B(3,.0)=MIN( "79", A+"8" )
|         Then:  C(3,.0)=A+"8"
|         Then:  D(3,.0)=MIN("79",C)
|         Then:  SHOW "A="{A<"B="{B<"C="{C<"D="{D
|  
|         Gives the following result:
|  
|                             A=25 B=33 C=33 D=33
| 
|          It demonstrate that it doing math within () works for MIN.
|          
|          Perhaps filePro has a bug parsing the hypen treating it like an 
|          argument-separator instead of a minus-sign, but I would have 
|          thought nesting the math in parenthesis such as with ......
| 
|             B(3,.0)=MAX( "1", (A-"8") ),   would correct that.

Maybe you should have.

Maybe you have a point there.
