Something like this?

#!/bin/ksh

str="QQQQQQQ:ABDE:FFFFFF:GGGGG"

set $(echo $str | tr ':' ' ')

if [[ $2 =~ "A" ]]
then
  VAR=yes
fi

if [[ $2 =~ "B" ]]
then 
  VAR1=yes
fi

if [[ $2 =~ "C" ]]
then 
  VAR2=yes
fi

Why did you use [[...]] instead of [...]

if [[ $2 =~ "C" ]]

if [ $2 =~ "C" ]

# str="QQQQQQQ:ABDE:FFFFFF:GGGGG"
# set $(echo $str | tr ':' ' ')
# [[ $2 =~ "A" ]] && echo yes
/usr/bin/ksh: 0403-057 Syntax error: `=~' is not expected.

With the test command [[...]] you can use extended regular expressions like [[ $2 =~ "A" ]].

The test command [[..]] with an ERE works with ksh93 not with ksh88.
