Directory Searching

Sunbelt's PL/B implementations use a feature unique to most programming language environments. That is, the ability to search multiple drives and directories for data files and user programs. Through use of the PLB_PATH environment variable, it is possible to allow the PL/B environment to have more than just the current directory considered as the default for any file creations, opens, or program chaining. Throughout the documentation, the phrase 'logged on drives' is used, referring to those drives that have been set in the PLB_PATH environment variable and the current directory. If the current drive is A and PLB_PATH was set to C:\SUNBELT\PLC;C:\SUNBELT\DEMO, the runtime will first search drive A for the file requested and then search only the two paths specified.
