Michael,
Have you seen the QWCRDTAA API? It might be what you are looking for. The TYPE, LENGTH and DECPOS attributes of the receiver data structure contain information about the type, length and number of decimal positions:
* Retrieve Data Area (QWCRDTAA) API
d QWCRDTAA...
d pr extpgm('QWCRDTAA')
d o_rcvVar 65535a options(*varsize)
d i_lenRcvVar 10i 0 const
d i_qDtaAra 20A const
d i_start 10i 0 const
d i_length 10i 0 const
d io_errCode 65535a options(*varsize)
*
* Format of Data Returned (attributes and value)
d rtvDtaAra_t ds qualified template
d bytRet 10i 0
d bytAvl 10i 0
d type 10a
d lib 10a
d length 10i 0
d decPos 10i 0
d value 2000A
You may remove the "value" field of the " rtvDtaAra_t" data structure if you are not interested in the value of the data area.
Thomas.
