Maybe you should reverse your initial matrix : ....


Code:
$cat my
var_Site,SITE-A1,SITE-A2,SITE-A3,SITE-B1,SITE-B2,SITE-C2,SITE-C3,SITE-C4
var_Name,HOST-A1,HOST-A2,HOST-A3,HOST-B1,HOST-B2,HOST-C2,HOST-C3,HOST-C4
var_Ipaddress,11.11.11.1,11.11.11.2,11.11.11.3,22.22.22.1,22.22.22.3,33.33.33.1,33.33.33.2,33.33.33.3
var_Port,22,22,22,22,22,22,22,22
var_Location,Bay1,Bay5,Bay3,Bay1,Bay2,Bay4,Bay2,Bay3
var_City,London,London,London,Rome,Rome,Paris,Paris,Paris
var_Comment,Comment1,Comment2,Comment3,Comment4,Comment5,Comment6,Comment7,Comment8
var_Data,Data1,Data2,Data3,Data4,Data5,Data6,Data7,Data8
var_String,String1,String2,String3,String4,String5,String6,String7,String8
$

might be easier to read for further processing if you take it that way :

Code:
$tr , "\n" <my | pr -t -9 -s" "
var_Site var_Name var_Ipaddress var_Port var_Location var_City var_Comment var_Data var_String
SITE-A1 HOST-A1 11.11.11.1 22 Bay1 London Comment1 Data1 String1
SITE-A2 HOST-A2 11.11.11.2 22 Bay5 London Comment2 Data2 String2
SITE-A3 HOST-A3 11.11.11.3 22 Bay3 London Comment3 Data3 String3
SITE-B1 HOST-B1 22.22.22.1 22 Bay1 Rome Comment4 Data4 String4
SITE-B2 HOST-B2 22.22.22.3 22 Bay2 Rome Comment5 Data5 String5
SITE-C2 HOST-C2 33.33.33.1 22 Bay4 Paris Comment6 Data6 String6
SITE-C3 HOST-C3 33.33.33.2 22 Bay2 Paris Comment7 Data7 String7
SITE-C4 HOST-C4 33.33.33.3 22 Bay3 Paris Comment8 Data8 String8
$

And then just

Code:
$tr , "\n" <my | pr -t -9 -s" " | (read a; while read a; do set -- $a ; echo "Test connection to $2 from $5 in $6
> Use $3 $4 to connect
> Note: Apply this $8 and $9
> Check: $7"; done )
Test connection to HOST-A1 from Bay1 in London
Use 11.11.11.1 22 to connect
Note: Apply this Data1 and String1
Check: Comment1
Test connection to HOST-A2 from Bay5 in London
Use 11.11.11.2 22 to connect
Note: Apply this Data2 and String2
Check: Comment2
Test connection to HOST-A3 from Bay3 in London
Use 11.11.11.3 22 to connect
Note: Apply this Data3 and String3
Check: Comment3
Test connection to HOST-B1 from Bay1 in Rome
Use 22.22.22.1 22 to connect
Note: Apply this Data4 and String4
Check: Comment4
Test connection to HOST-B2 from Bay2 in Rome
Use 22.22.22.3 22 to connect
Note: Apply this Data5 and String5
Check: Comment5
Test connection to HOST-C2 from Bay4 in Paris
Use 33.33.33.1 22 to connect
Note: Apply this Data6 and String6
Check: Comment6
Test connection to HOST-C3 from Bay2 in Paris
Use 33.33.33.2 22 to connect
Note: Apply this Data7 and String7
Check: Comment7
Test connection to HOST-C4 from Bay3 in Paris
Use 33.33.33.3 22 to connect
Note: Apply this Data8 and String8
Check: Comment8
 $


Of course you would have to adapt it to your need especially if the Comment contains some space, but i gave this shot just for the idea
The first "read a" is just to skip the header line.
