How can a perl script generate an output file based on the value of some parameters existing in the the input file but their value defined in a seperate config file. In the example shown below, I am using OPT: as a keyword to find such options and then using split I am able to extract the SEL_BLOCK keyword. But the issue is I am unable to check the value of SEL_BLOCK and so unable to generate the text in the output file.
This block will only get printed in the output file if value of SEL_BLOCK = 1 in the configuration file.
SEL_BLOCK = 1
