For convenience, copybook javatypes.cpy defines a set of COBOL data types corresponding to Java data types - you can use these as a shorthand way of declaring data items for use with Java in your COBOL programs. You can find the copybook in your $COBDIR/cpylib directory.
These typedefs all start with the prefix "j" and are shown in the following table:
| Typedef | COBOL Type |
|---|---|
| jbyte | pic s99 comp-5 |
| jshort | pic s9(4) comp-5 |
| jint | pic s9(9) comp-5 |
| jlong | pic s9(18) comp-5 |
| jboolean
JNI-TRUE is true JNI-FALSE is false |
pic 99 comp-5 |
| jchar | pic 9(4) comp-5 |
| jfloat | comp-1 |
| jdouble | comp-2 |
| jobject | pointer |
| jbigdecimal | pic s9(19)v9(19) comp-3 |
| jbiginteger | pic s9(38) comp-3 |
| mf-sql-date
(in javatypes.cpy) |
0x jyear pic 9(4).
0x filler pic x. 0x jmonth pic 99. 0x filler pic x. 0x jday pic 99. |
| mf-sql-time
(in javatypes.cpy) |
0x jhour pic 99.
0x filler pic x. 0x jminute pic 99. 0x filler pic x. 0x jseconds pic 99. |
