TAPEMAC
TAPEMAC Use the TAPEMAC command to create a CMS MACLIB from an unloaded
partitioned data set (PDS) from a tape created by the IEHKOVE utility
program under as. The PDS from which the tape was created can be
blocked, but the logical record length must be 80. The format of the
TAPEMAC command is:
r -------------------------------, I TAPEMAC fn [ (options ••• [) ]] 2.E:tiQ!!§: , I I I I L
fn
r , r , ITAPn"ITEMCT yyyyy, L .J L .J , I I , specifies the filename of the first, or only, CMS MACLIB to be
created on the A-disk. If fn MACLIB already exists on the
A-disk, the old one is erased; no warning messaqe is issued.
TAPn specifies the symbolic address of the tape, where n is a number
between 1 and 4 corresponding to virtual device addresses 181
through 184, respectively. The default is TAP1.
ITEMCT VYVYV specifies the item count threshold of each MACLIB to be
created, which is the maximum number of records to be written
into each file. yyyyy is a number between 0 and 62500 (commas
are not allowed) • If ITEMCT is not specified, the default is 50000. Tape records are read and placed into fn MACLIB until the file size
exceeds the ITEMCT (item count); loading then continues until the
end of the current member is reached. Then another CMS file is
created; its filename consists of the number 2 appended to the end
of the filename specified (fn) if the filename is seven characters
or less. The appended number overlays the last character of the
filename if the name is eight characters lonq. Loading then
continues with this new name. For example, if you enter the
command:
tapemac mvlib
you may create files named MYLIB MACLIB, KYLIB2 MACLIB, MYLIB3 MACLIB, and so on.
This process continues until up to nine CMS files have been
created. If more data exists on the tape than can fit in nine CMS files, processing is terminated with the error message DMSTMA139S. The maKimum size of the unloaded PDS which can be loaded into CMS MACLIBs would be approximately 9 times 62500 or 584,500 records. 192 VM/370 eMS Command and Macro Reference
