[mv] Problem with [calc] and [scratch] variables

[Ramsey French <rammjet@mac.com>]

Dear List,

I have looked in the list archives and cannot resolve this problem.

When I [calc] two [scratch] variables and place the result into a [scratch]
variable, an extra space or unprintable character ends up prepended to the
final [scratch] variable.  This presents a problem when testing with [if] or
using it as a key for searching in a table.

Here are examples of my tests:

This works:
    [if type=data term="frames::subcat_name::13"]

This works:
    [set my_test]13[/set]
    [if type=data term="frames::subcat_name::[scratch my_test]"]

This works:
    [seti my_test][calc]10+3[/calc][/seti]
    [if type=data term="frames::subcat_name::[scratch my_test]"]

This FAILS:
    [set my_var1]10[/set]
    [set my_var2]3[/set]
    [seti my_test]
        [calc][scratch my_var1]+[scratch my_var2][/calc]
    [/seti]
    [if type=data term="frames::subcat_name::[scratch my_test]"]


Looking closer:

Placing this into HTML:
    [seti my_test][calc]10+3[/calc][/seti]
    this_has_no_space=[scratch my_test]

yields    
   this_has_no_space=13

However, putting this in HTML:
    [set my_var1]10[/set]
    [set my_var2]3[/set]
    [seti my_test]
        [calc][scratch my_var1]+[scratch my_var2][/calc]
    [/seti]
    [seti my_test2]
        [[calc]return'[scratch my_var1]+[scratch my_var2]'[/calc]]
    [/seti]
    this_has_a_space=[scratch my_test]
    what_have_we_here=[scratch my_test2]

yields:
    this_has_a_space= 13
    what_have_we_here= [10+3]
    (notice a space between "=" and "13" and "[10+3]")


Any suggestions?

Thanks,

Ramsey French
