Function
Finds the active file table block whose filename, file­
type, and filemode match the one supplied by the caller.
Finds the next or first AFT block in the active file
table.
Finds an empty block in the active file table or adds a
new block from free storage to the active file table,
if necessary, and places a file status entry (if given)
into the AFT block.
Removes an AFT block from the active file table and re­
turns it to free storage if necessary.
Generates a macro library, adds macros to an existing
library, and lists the dictionary of an existing macro
library.
creates a text library, adds text files to an existing
text library, creates a disk file that lists the
control section and entry point names in a text
library.or types, at the terminal, the control section
and entry point names in a text library.
Begins execution of a group of programs loaded into
real storage. Definition of all undefined programs is
established at location zero. Entered from the START coamand or internally from DMSLDRB LDT routine if START is specified.
Processes TEIT files that may contain the following
cards: SLC, lCS, ESD, TXT, REP, RLD, END, tDT, LIERARY, and ENTRY. Entered from DMSLDP when the load function
is requested.
Does the processing required by various loader routines when an invalid card is detected in a text file.
Does the processing required when a fatal I/O error is detected in a text file.
Lists information about specified data sets residing on
an OS disk. Processes the LlSTDS command. Finds a specified 40-byte FST entry within the FST blocks for read-only or read/write disks.
Entered from DMSLDRB if not a dynamic load. Frees all
the TITLlB blocks on the TXTLIE chain.
Reads TITLlB directories into a chain of free storage
directory blocks. Entered from DftSLDRB. Searches TEXT libraries for undefined symbols and
closes the libraries.
