Re^3: Checking value of an extracted variable

[r.biswas]

I also like to point out that in the input file the keyword will be declared as below

Input.txt(input file) 
OPT: SEL_BLOCK [ 
 some text to be copied to output file
 if SEL_BLOCK = 1
]

SEL_BLOCK will be defined in a config file which can be included in the perl script. The script will have visibilty of the value of SEL_BLOCK and take appropriate actions(copying contents from input to output file).
