In bash you can use printf -v like this:

Code:
function getParams {
for param in $@
do
   printf -v "$param" "%s" "$(./db2 +w -x "SELECT PARM_VALUE_TXT FROM ${FRMWRK_DB_SCHEMA}.JOB_PARM WHERE PARM_NM='$param' WITH UR")"
done
}

getParams parm1 parm2 parm3

PAPI_get_overflow_event_index(3)				       PAPI					  PAPI_get_overflow_event_index(3)

NAME
PAPI_get_overflow_event_index - converts an overflow vector into an array of indexes to overflowing events SYNOPSIS
Detailed Description @param EventSet an integer handle to a PAPI event set as created by PAPI_create_eventset @param overflow_vector a vector with bits set for each counter that overflowed. This vector is passed by the system to the overflow handler routine. @param *array an array of indexes for events in EventSet. No more than *number indexes will be stored into the array. @param *number On input the variable determines the size of the array. On output the variable contains the number of indexes in the array. @retval PAPI_EINVAL One or more of the arguments is invalid. This could occur if the overflow_vector is empty (zero), if the array or number pointers are NULL, if the value of number is less than one, or if the EventSet is empty. @retval PAPI_ENOEVST The EventSet specified does not exist. @par Examples void handler(int EventSet, void *address, long_long overflow_vector, void *context){ int Events[4], number, i; int total = 0, retval; printf("Overflow #%d Handler(%d) Overflow at %p! vector=0x%llx0, total, EventSet, address, overflow_vector); total++; number = 4; retval = PAPI_get_overflow_event_index(EventSet, overflow_vector, Events, &number); if(retval == PAPI_OK) for(i=0; i<number; i++) printf("Event index[%d] = %d", i, Events[i]);} * @see PAPI_overflow Author Generated automatically by Doxygen for PAPI from the source code.
