Converts and validates a hex string.
Converts and validates a decimal string.
Converts a hex fullword to and generates an EBCDIC representation of it, suppresses leading zeroes
to a minimum count, which is optionally supplied by the
caller.
Converts EBCDIC to the System/370 TOD value.
Converts System/370 TOD to an EBCDIC date and time. Gets inactive successor sFool file.
Inspects newly arrived files.
Brings in a link's pending tags.
Gets a routing table entry.
Gets link table entry.
Gets a free tag queue element.
Returns a tag queue element.
Builds a file tag from hYFervisor information. Sets a file tag into a link queue immediately before
the first tag of numerically higher priority (lower
real priority). Selects a file to be read from a link queue.
Locates a file with spoolid matching the one sUFplied by the caller, within the internal file tag queues.
Gets a virtual spool device. Undefines a virtual spool device.
Changes VM/370 file attributes.
Issues the VM/370 CLOSE command for a device.
Purges an inactive reader file from the VM/310 spool. Sets VM/370 virtual spool device options. Sets a VM/370 tag for a virtual spool device. Sets a VM/370 tag for an inactive spool file.
This module is part of the REI system control task. DMTCMX is called in several places in DMTREX, which is
the main REI control routine. DMTCMX accepts an BECDIC string and executes the RSCS command that the string
represents.
Calls the necessary individual command proccessing
routine.
Passes a command element to another task via the ALERT
task-to-task communications interface.
Decodes the next keyword cn the input command line. 3-48 IBM VM/370: System Logic and Problem Determination--Volume 3

Function
Finds the link table entry implied by the first keyword
in the command line described by the calling rcutine's
register parameters.
converts and validates a hex string.
converts a hex fullword to decimal and generates an
EBCDIC representation of it. It suppresses leading
zeros to a minimum count, which is optionally sUPFlied by the calling routine.
Locates a file, within the internal file tag queues,
with a spoolid matching that supplied by the calling
routine.
Converts a System/370 format TOD to EBCDIC data and time. Scans an EBCDIC line and frames the next parameter on
the line.
Contains various reentrant routines used by RSCS tasks. Scans the link table chain and returns a link table
address.
Gets a free page of main storage.
Returns a page of main stcrage. Stacks message elements in a LIFO stack fer later
processing. If no room is available in the current
page, a new page is fetched if there are at least five
free pages remaining. If five free pages are not
remaining, an error condition is returned.
All tasks except REX are allowed only three Fages of
storage to stack messages. Unstacks message elements from the message queue for
this task. If none are queued an error conditicn is
returned.
Converts a System/370 format TOD to EBCDIC data and time. Creates new tasks under ftSUP. Reads one dASD block from a CMS disk.
Does initial work prior to reading a CMS file.
Gets the next CftS file item. RSCS Directories 3-49
