Translating Data with TMA TCP gateway
Oracle Tuxedo Mainframe Adapter for TCP CICS User Guide 2-9
Note: Oracle Tuxedo provides a field type named dec_t that supports decimal values within
VIEWs. The TMA TCP gateway product translates these fields into machine independent
representations of packed decimals. For example,
dec_t(m,n) becomes
S9(2*m-(n+1))V9(n) COMP-3. Therefore, a decimal field with a size of 8,5
corresponds to
S9(10)V9(5) COMP-3.
The following table summarizes the translation rules between C and IBM/370 data types.
LONG
