Example of specifying keywords

Issue an FCQUERY request with the DEVN, QRYSIZE, FORMAT and QRYINFO keywords.

1. Define the keywords in variable INOUT, which is the stem of a REXX compound variable:

   INOUT.0 = 4
   INOUT.1 = 'DEVN(0A00)’
   INOUT.2 = 'QRYSIZE(2000)’
   INOUT.3 = 'FORMAT(FQMAP)’
   INOUT.4 = 'QRYINFO()’

   Note that the value of INOUT.0 is a count of the number of values in the stem.

2. Call ANTTREXX with an FCQUERY request, specifying variable INOUT:

   CALL ANTTREXX 'FCQUERY’ , 'INOUT’

3. Display the information from the query. The keyword for the output field is QRYINFO, which is in INOUT.4.

   SAY INOUT.4
