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

Translated to S9(9) COMP
