General Rules for Adapter Commands
Following is a list of the general rules that apply when specifying adapter
commands:
♦ Each command must begin with a hyphen.
♦ Command characters can be upper-case, lower-case, or mixed-case.
♦ Command strings are parsed in left-to-right order.
♦ The order of commands is not important.
♦ Command files can contain multiple lines. Line breaks can be used in place of
the required space that must exist between commands. The line breaks are
converted to spaces before processing.
♦ Space characters:
! Spaces preceding the first command are ignored.
! At least one space between commands is required
(for example: -KEEP -TRACE).
! A space is required preceding a variable value
(for example: -TRACE+S
full_pathname ).
♦ The value of the Command setting (adapter-specific commands) in input and
output cards and in a
GET or PUT function within a map rule may not exceed
260 bytes. The expansion of the resource value is included in this limitation.
For platform-specific information about using specific adapter commands with
execution commands, refer to the following:
♦ For Windows Sources and Targets on the Command Line
♦ For UNIX Sources and Targets on the Command Line
Command Syntax Summaries
A syntax summary is a comprehensive list of the adapter-specific commands
organized for use with data sources and data targets. Syntax notation, as applied
to all command documentation, indicates required and optional commands, as well
as options available for each command.
Required commands appear at the top of the list. Optional commands appear in
brackets [ ]. Command dependencies are also noted when commands appear on
the same line.
