At the start of both scripts, let them know how they should run i.e. interpreter.
For bash, put first line as #!/bin/bash
Write down your logic.
Call ksh script.
In ksh script, put first line as #!/bin/ksh
Once ksh exits, control will be regained by bash.
Note: Location of ksh and bash can vary depending upon system.
You need to study further, if scripts are passing data to each other.
It would be better if you provide complete flow with code (if feasible).

diff3(1) User Commands diff3(1)
NAME
diff3 - 3-way differential file comparison
SYNOPSIS
diff3 [-exEX3] filename1 filename2 filename3
DESCRIPTION
diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes:
==== all three files differ
====1 filename1 is different
====2 filename2 is different
====3 filename3 is different
The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways:
f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.
f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1.
The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
The following command will apply the resulting script to filename1.
(cat script; echo '1,$p') | ed - filename1
OPTIONS
-e Produce a script for the ed(1) editor that will incorporate into filename1 all changes between filename2 and filename3 (that is,
the changes that normally would be flagged ==== and ====3).
-x Produce a script to incorporate only changes flagged ====.
-3 Produce a script to incorporate only changes flagged ====3.
-E Produce a script that will incorporate all changes between filename2 and filename3, but treat overlapping changes (that is,
changes that would be flagged with ==== in the normal listing) differently. The overlapping lines from both files will be inserted
by the edit script, bracketed by <<<<<< and >>>>>> lines.
-X Produce a script that will incorporate only changes flagged ====, but treat these changes in the manner of the -E option.
USAGE
See largefile(5) for the description of the behavior of diff3 when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
