Script to read file and locate specific lines and do some math with the numbers.

[cadi56]

Hi

I was just given an assignment to read a file with lines like this:

21126.43870 HEART_PARAMETER_CHANGE_EVENT ParamID:111 ParamVal:59(0x3B)
21126.44470 HEART_BEAT_EVENT CH:RV Cause:Conducted LT:857 WFIndex:7 PPAMP:100
21126.44670 HEART_PARAMETER_CHANGE_EVENT ParamID:112 ParamVal:59(0x3B)
HEART_SCENARIO_STRING_DISPLAY Strlen:31 String:4.5.7.1 TC1.0: AV SEARCH FEATUR
21127.31369 HEART_BEAT_EVENT CH:RA Cause:Normal LT:869 WFIndex:7 PPAMP:100
21127.41469 HEART_BEAT_EVENT CH:RV Cause:Conducted LT:970 WFIndex:7 PPAMP:100

What I need to do is to find the lines with RA in followed by RV and subtract the value of LT on the RV line from the value of LT on the RA line and write the value to another text file.

I know that someone in this forum has the ready know how and could save me tones of time.

Thanks

Sorry, but it's against the forum rules to post homework questions here:

You'll need to complete your own assignment.
