Hi all. I am trying to parameterize my OMB scripts. For now I am only able to pass one type of parameter, For example in the script below I can parameterize the mapping name. So even If I pass 3 mapping names I will import MDX files and deploy for all 3 mappings.
I want to improve this and I want to pass other parameters such as passwords and schema names also. How would I be able to do that? How can I pass different type of parameters such as schema name, password and mapping name and reference to them separately from the script?

set MAPLIST $argv
OMBCONOMBCONNECT DWPROD/DWPROD@cakir:1521:orcl USE REPOSITORY 'OWBDB_SYS'OMBCC 'MY_PROJECT'
OMBCONNECT CONTROL_CENTER
OMBCOMMIT
foreach mapName $MAPLIST {
OMBIMPORT MDL_FILE 'C:/tfsroot2/Interfaces and Extracts/branches/Interfaces and Extracts1.1/000 - OWB Prototype/deploy/ora.stg/mappings/$mapName.mdx' USE UPDATE_MODE MATCH_BY NAMES OUTPUT LOG TO 'C:/tfsroot2/Interfaces and Extracts/branches/Interfaces and Extracts1.1/000 - OWB Prototype/deploy/ora.stg/mappings/$mapName.log'
