I have two:
Variables:
request$input1 = “00”
request$input2 = “0000”
<@IF expr=”
‘A<@VAR input1>’ = ‘A<@VAR input2>’
“>
By placing an arbitrary letter before the variables, you will force TeraScript
to internally compare them as strings. This will be False.
OR
<@IF expr=”
<@CIPHER hash md5 <@VAR input1> = <@CIPHER hash md5 <@VAR
input2>>
“>
Since the MD5 hash of 0 is different from 00, this will be False. This trick
also allows you to do case sensitive string comparisons, where @IF normally is
case insensitive.

PS. Both of these short-comings are issues that should be corrected. I’ll add
them to my to-do list.

Any ideas?

This is what I need...
0 = 0 True
00 = 0 False
Simply changing the TRUE and FALSE values does not work. Both of these equate
to TRUE.
All of these equate to true too...
<@IF EXPR="'000' = '0'" TRUE ="true" FALSE="false">
<@IF EXPR="'0' = '0'" TRUE ="true" FALSE="false">
<@IF EXPR="00000 = 0" TRUE ="true" FALSE="false">
<@IF EXPR="0 = 0" TRUE ="true" FALSE="false">
<@IFEQUAL "00" "0000">true<@ELSE>false</@IF>
<@IFEQUAL "0" "0">true<@ELSE>false</@IF>

John,
It seems to me like you should reverse your TRUE and FALSE values.
