DLBL Use the DLBL command: • In CMS/DOS, to define DOS and CMS sequential disk files for program
input/output; to identify DOS files and libraries; to define and
identify VSAM catalogs, clusters, and data spaces; and to identify VSAM, DOS, or CMS files used for VSAM program input/output and access
method services functions. • In eMS, to define and identify VSAM catalogs, clusters, and data
spaces; to identify VSAM files used for program input/output; and to
identify input/output files for AMSERV. The format of the DLBL command is:
