Parse

To break up a string into component parts so that each part can be handled separately. The parts are normally separated by a particular character such as a comma or tab.

Eg. the line:-

Name,Address,Telephone,Fax

would be parsed into four separate strings:-

Name
Address
Telephone
Fax

and processing could continue using each portion.

The normal method is to break the string into a series of array elements.

Just to make things slightly difficult, there is an OPL keyword - PARSE$ - that creates all the component parts of a filename (drive,directory,file) from it's simple name in the current directory. In this case the starting string doesn't actually contain all the sections extracted by the command and relies on the operating system to provide the missing bits.
