Using = and ?
CICS V2
CICS V2 uses an equal sign (=) and a question mark (?) to initiate an action or a query
(see Table 72).
CICS V3.00 (or later)
CICS V3.00 does not use symbols to initiate an action or a query. It assumes that a
command followed by text characters is an action, and any command alone is a query, as
shown in the following example.
Compatibility between CICS V2 and V3.00 (or later)
For backwards compatibility, CICS V3.00 replaces any equal sign (=) and question mark
(?) that is in the command line with a space, unless the symbol is preceded by a \, or it is
within double quotes.
