|
|
* 04/10/97 aliu Made to work on AIX. Added stoi to replace wtoi.
|
|
* 06/11/97 helena Fixed addPattern to take the pattern correctly.
|
|
* 06/17/97 helena Fixed the getPattern to return the correct pattern.
|
|
* 07/09/97 helena Made ParsePosition into a class.
|
|
* 02/22/99 stephen Removed character literals for EBCDIC safety
