Hello Bubbajoe,
The input should be a file with many data sets separated by blank line as shown in my previous post.Check the first data set if Col5 value for a specific record is increasing e.g Fre 42:86 and nie 25:76. For both these records in first data set the Col5 value is increasing. As we can see in the following first data set.
0.85 0.07 Fre 42:86 25
0.73 0.03 frp 21:10 28
0.64 0.04 Fre 42:86 63
0.47 0.08 nie 25:76 32
0.37 0.01 veb 00:71 26
0.63 0.48 Fre 42:86 65
0.65 0.32 frp 21:10 19
0.47 0.08 nie 25:76 43

Now read 2nd data set and check if for these records(Fre 42:86 and nie 25:76) the Col5 value is greater than 30. So if we look at the following 2nd data set, all the Col5 values for record(Fre 42:86) which was selected from first data set is greater than 30 and for record (nie 25:76) there is a Col5 value in 2nd data set which is less than 30 (0.53 0.56 nie 25:76 20). So we found one record which fulfilled the conditions(count=1).
0.53 0.56 nie 25:76 52
0.32 0.43 veb 00:71 18
0.85 0.07 Fre 43:86 40
0.65 0.32 frp 21:10 30
0.85 0.07 Fre 43:86 50
0.53 0.56 nie 25:76 20
0.65 0.32 frp 21:10 40
0.85 0.07 Fre 43:86 50

Similarly,now we will check the 2nd data set if Col5 value for a specific record is increasing.If we found any record in 2nd data set then we will read the 3rd data set and check if the Col5 value for those record in greater than 30. If true then again just count it.
and so on for next data sets.
I hope this time you got my problem but let me know if you still have any confusion.
Thank you so much for your time and cooperation.
Regards,
Ubee

NAME
srec_emon52 - Elektor Monitor (EMON52) file format DESCRIPTION
This format is used by the monitor EMON52, developed by the European electronics magazine Elektor (Elektuur in Holland). Elektor wouldn't be Elektor if they didn't try to reinvent the wheel. It's a mystery why they didn't use an existing format for the project. Only the Elektor Assembler will produce this file format, reducing the choice of development tools dramatically. Records All data lines are called records, and each record contains the following four fields: +---+------+---+-----------+------+ |cc | aaaa | : | dd ... dd | ssss | The field are defined as follows: +---+------+---+-----------+------+ cc The byte count. A two digit hex value (1 byte), counting the actual data bytes in the record. The byte count is separated from the next field by a space. aaaa The address field. A four hex digit (2 byte) number representing the first address to be used by this record. : The address field and the data field are separated by a colon. dd The actual data of this record. There can be 1 to 255 data bytes per record (see cc) All bytes in the record are separated from each other (and the checksum) by a space. ssss Data Checksum, adding all bytes of the data line together, forming a 16 bit checksum. Covers only all the data bytes of this record. Please note that there is no End Of File record defined. Byte Count The byte count cc counts the actual data bytes in the current record. Usually records have 16 data bytes. I don't know what the maximum number of data bytes is. It depends on the size of the data buffer in the EMON52. Address Field This is the address where the first data byte of the record should be stored. After storing that data byte, the address is incremented by 1 to point to the address for the next data byte of the record. And so on, until all data bytes are stored. The address is represented by a 4 digit hex number (2 bytes), with the MSD first. Data Field The payload of the record is formed by the Data field. The number of data bytes expected is given by the Byte Count field. Checksum The checksum is a 16 bit result from adding all data bytes of the record together. Size Multiplier In general, binary data will expand in sized by approximately 3.8 times when represented with this format. EXAMPLE
Here is an example of an EMON52 file: 10 0000:57 6F 77 21 20 44 69 64 20 79 6F 75 20 72 65 61 0564 10 0010:6C 6C 79 20 67 6F 20 74 68 72 6F 75 67 68 20 61 05E9 10 0020:6C 6C 20 74 68 69 73 20 74 72 6F 75 62 6C 65 20 05ED 10 0030:74 6F 20 72 65 61 64 20 74 68 69 73 20 73 74 72 05F0 04 0040:69 6E 67 21 015F SEE ALSO
