ksh93 if statement gives "not found" error
Why do I get the error on the second example?.

This works:
Code:
if [[ "a" = "a" ]];then
> echo "true"
> else
> echo "false"
> fi
true

This doesn't, and gets the error shown:
Code:
if [[ "a" = "a" ]];then
> b=1
> else
> b=0
> fi
-ksh93: line 2: .
b=1: not found.

You sure you didn't make a mistake and use backspace while typing b=1

Perhaps you typed b- then backspace then =1 (I get the above error if I do that) but fine if I type without making a correction.

Code:
if [[ "a" == "a" ]];then
> b-^H=1
> else
> b=0
> fi
ksh93: line 2: .
b=1: not found.
