Declaring constants

 

Most constants are declared as equates in macro CMQA. However, the following constants cannot be defined as equates, and these are not included when you call the macro using default options:

• MQACT_NONE

• MQCI_NONE

• MQFMT_NONE

• MQFMT_ADMIN

• MQFMT_COMMAND_1

• MQFMT_COMMAND_2

• MQFMT_DEAD_LETTER_HEADER

• MQFMT_EVENT

• MQFMT_IMS™

• MQFMT_IMS_VAR_STRING

• MQFMT_PCF

• MQFMT_STRING

• MQFMT_TRIGGER

• MQFMT_XMIT_Q_HEADER

• MQMI_NONE

To include them, add the keyword EQUONLY=NO when you call the macro.

CMQA is protected against multiple declaration, so we can include it many times. However, the keyword EQUONLY takes effect only the first time that the macro is included.
