a keyword search with upto 3 addtional keywords close to primary keyword

[Paul Purvis]

a console program to find keywords, display them, then allow you to view the whole file and return back to the point in the search before viewing the whole file.

notepad is the program used to view the whole file or it can be edited with a binary editor

a tool to search a file or files using a wild card in a single directory using up to 4 keywords with the first keyword being a primary keyword.

program will find and display 13 lines of a file with the line in middle being the line which holds the primary keyword.
if additional keywords are given in the search, up to 3 of them, the results of the search will be where the additional keywords are up to 6 lines away from the primary keyword.

option to pick where the additional keywords must be found.
all keywords on a single line
or
the line on which the primary keyword is found and any line 6 lines before
the line on which the primary keyword is found and any line 6 lines after
the line on which the primary keyword is found and any line 6 lines before and 6 lines after.

all keywords entered must be found for a match to be made.

i added some code to the program while placing this thread, program should work
