Well, considering that pd-ksh will fail in the same manner that bash does, I'm not sure that this is any great loss. But just use
#! /usr/bin/ksh
on Linux to invoke pd-ksh. I believe that the real ksh is available for Linux, but I don't know how you get it. You need to stop doing
some-command | read this that
to get your script to work with bash or pd-ksh. If you can't think of anything else,
some-command > tempfile
read this that < tempfile
rm tempfile
should do it.

NAME
let - shell built-in function to evaluate one or more arithmetic expressions
SYNOPSIS
ksh
let arg...
ksh93
let [expr...]
DESCRIPTION
ksh
Each arg is a separate arithmetic expression to be evaluated.
ksh93
let evaluates each expr in the current shell environment as an arithmetic expression using ANSI C syntax. Variables names are shell vari-
ables and they are recursively evaluated as arithmetic expressions to get numerical values. let has been made obsolete by the ((...)) syn-
tax of ksh93(1) which does not require quoting of the operators to pass them as command arguments.
EXIT STATUS
ksh
ksh returns the following exit values:
0 The value of the last expression is non-zero.
1 The value of the last expression is zero.
ksh93
ksh93 returns the following exit values:
0 The last expr evaluates to a non-zero value.
>0 The last expr evaluates to 0 or an error occurred.
