perl convertor

[All4terenity]

Dear WISKI users, administrators.

I had one issue with import of zrxp file. It was from another institute and could not change anything in it. The issue was parameter name. It had space between words ( Air temperature) and wiski generated import number with space. But space can not be in it. Couldn't change the path cause it is not from my system. So there were no way to import it.
I solved it by putting it through Kirolling Optimizer. Kiro has one option "replace header" so I used it. Files came up with the header I wanted with parameter name I wanted ( AirTemperature instead of Air temperature) and import was piece of cake.
I dont like using Optimizer cause it takes double time to process the files and use much memory and space. So I thought of making converter, integrated it system and use it to manipulate file.

It should be some simple code, just to change one thing in second row in file. But I am not good in Perl. Is there anyone who has done it before or know how to write it? I would be so grateful. Also I am in disposal if I can help in anything ( some settings, TS, converters...)
