Mee too. The stuff you posted makes it even more complex than it already is.

Based on the current TS syntax I could imagine a more simplifying approach:

True, false and positive ould stay as is once the useless "value" has been
removed. stdWrap could stay as well.

if.isTrue = 1
if.isFalse = 0
if.isPositive = 2

if.isTrue.data = GPvar:print
if.isFalse.data = GPvar:print
if.isPositive.data = GPvar:print

The problem with isGreaterThan and isLessThan and isInList is just the order
of values and equals could stay as is. So changing the order should be
enough - value should be treated just like it is done in TEXT elements and
the operator should not get an additional value but still stdWrap
properties:

if.value = 2
if.equals = 2

if.value = 2
if.isGreaterThan = 1

if.value = 1
if.isLessThan = 2

if.value = 1
if.isInList = 1,2,3

OR

if.field = fieldname
if.equals = 2

if.field = fieldname
if.isGreaterThan = 1

if.field = fieldname
if.isLessThan = 2

if.field = fieldname
if.isInList = 1,2,3

OR

if.field = fieldname
if.equals.field = fieldname2

if.field = fieldname
if.isGreaterThan.field = fieldname2

if.field = fieldname
if.isLessThan.field = fieldname2

if.field = fieldname
if.isInList.field = fieldname2


Negate should be kicked completely in favour of a simple "not"

if.not.isPositive.data = GPvar:print

if.value = 1
if.not.equals = 2

if.value = 1
if.not.isGreaterThan = 1

if.value = 2
if.not.isLessThan = 2

if.value = 4
if.not.isInList = 1,2,3

This would offer the possibility to AND "not" and "non not" operators as
well:

if.value = 1
if.isLessThan = 2
if.not.isInList = 1,2,3

Introducing "or" and "and" instead of just "not" would open up even more
possibilities.

if.value = 1
if.isLessThan = 2
if.or.isGreaterThan = 4

if.value = 1
if.isLessThan = 4
if.and.not.isLessThan = 2
if.or.equals = 2

This would be closer to the logic "real" programmers are used to but still
as close to the current version as possible, while simplifying the whole
stuff a bit for both programmers and integrators.

Just my 2 cents
