A cob option takes the form:
flag-intro flag-letter [parameter]
flag-intro flag-letter[flag-letter]... [parameter]
where the parameters are:
Parameters to directives given on the cob command line or in a directives file retain their case, but parameters to directives given in a $SET statement are converted to upper case.
You might need to set options as a system or user default and then to unset them again in specific instances. By specifying a hyphen after the flag letter with no intervening space, you can unset the following options: -c, -P and -U.
Options specified on the cob command line pass through the UNIX shell, which preprocesses certain characters such as space, asterisk (*), parentheses (), single (') and double (") quotation marks. To pass these special characters unchanged as part of an option, you must escape the shell processing, as follows:
To pass an equals sign (=) to the COBOL components, use two equals signs together (==).
The cob command treats single and double quotation marks in an option in the same way, regardless of whether the option is specified on the command line or in the cobopt file or COBOPT environment variable.
