It will save the value that is to be generated by the 
server in next accesing of the application.

web_reg_save_param()

web = webapplication(HTTP)
reg = Regestration
save = saving the next comming dynamic value into the       
parameter name
param = parameter

The web_reg_save_param() function registers a request to 
retrivew dynamic information from the downloaded page and 
save it to the above mentoned parameter name.

the above information is upto me, if any wrong plz excusive 
me.

web_reg_save_param()

web = webapplication(HTTP)
reg = Regestration
save = saving the next comming dynamic value into the       
parameter name
param = parameter

Please, note that web_reg_save_param function does not 
perform correlation. web_reg_save_param function just 
registers a request for correlation from the next server 
response. That's why web_reg_save_param function should be 
placed before action functions, such as: web_url, 
web_submit_form, and others.

1). Enable extended logging for LoadRunner parameters 
substitutions. It will be helpful for script debugging:
