New and changed commands
The following
EXEC
CICS WEB commands are enhanced when used by CICS® as an HTTP server:
- EXEC CICS WEB SEND
- EXEC CICS WEB RECEIVE
CICS Web support is designed to allow Web-aware application programs
that used these commands before
CICS Transaction Server for z/OS®, Version 3 Release 1 to
work unchanged, until you choose to migrate them to take advantage of the
enhancements that are now available.
The options that were available
on the WEB SEND command before
CICS Transaction Server for z/OS, Version 3 Release 1 are
CLNTCODEPAGE, DOCTOKEN, LENGTH, STATUSCODE and STATUSTEXT. In
CICS Transaction Server for z/OS, Version 3 Release 1:
- The name and function of the options DOCTOKEN, STATUSCODE and STATUSTEXT
is unchanged.
- The options CLNTCODEPAGE and LENGTH are supported for migration purposes
only, and their function is replaced by the new options CHARACTERSET and STATUSLEN
respectively.
- Some new options are available for enhanced functionality.

CICS Transaction Server for z/OS, Version 3 Release 1 are
CLNTCODEPAGE,
HOSTCODEPAGE,

and
TYPE. In
CICS Transaction Server for z/OS, Version 3 Release 1:
- The name and function of the options INTO, LENGTH, MAXLENGTH, NOTRUNCATE, SET,
