1 Verify the operands in the ZAP com- DMSZAP mand. If TXTLIB or LOADLIB is
specified, move the library names (up
to three) into LlBNAME1. If no
library name was specified, issue the
message: DMSZAPOO1E NO FILENAME SPECIFIED Other messages that may be issued if
the command line is in error are: DMSZAP014E INVALID FUNC- TION 'function' DMSZAP047E NO FUNCTION SPECIFIED DMSZAP070E INVALID PARA- METER 'param'
2 If options are specified, check for DMSZAP validity. If mutually exclusive options
or invalid options are specified, issue
the message: DMSZAPOO3E INVALID OPTION 'option'

be found, the message: DMSZAPOO2E FILE 'fn ft' NOT (See Diagrams 10-3, 10-4, and 10-5 for details.) Label Ref Notes SCAN LINE from the specified INPUT file (RDCARD2 routine). Save the control STLIB record in CDBUF. 6 Print the control record on the SYSOUT printer if the PRINT option
is in effect.
7 Check the control record for a valid key-
word. If the statement is blank or
the first character is an asterisk, return
control to READINP (step 4). Otherwise, compare the keyword to
keyword tables whose formats are:

3 Go to the open routine (PREOPLlB) DMSZAP to locate the member or module
and the CSECT desired.
4 Use the starting and ending addresses DMSZAP of the CSECT to determine the length
of the dump if not otherwise specified.
Go to the read text routine to read the

A. Open the file.
B. Find the CSECT. (See Diagram 10-6 for details.)
