[Q]: Библиотеки для программирования на Rexx

[A]: Sergey Shikov (2:5020/157.108)

Для начала - ydbautil. IMHO наиболее полная библиотека того, чего в REXX обычно недостает с начала работы. В настоящее время я пользуюсь Release 1.8.

Вторая библиотека - rxasync, предназначена для работы с COM-портами. Полный набор функций низкого уровня, т.е. без протоколов, упаковки, модемов.

Rxsocket - набор функций для работы с TCP/IP из REXX.

Rxipc - Inter Process Communication для REXX. Перекрывается возможностями ydbautil. Более подробно сказать что-либо сложно.

EPMBBS - пакет для написания макро к EPM на REXX и собственном макроязыке EPM-а.

Есть еще библиотеки, позволяющие использовать некоторый набор controls в PM-программах из REXX, обычно Message Box, Input Line с кнопками Ok и Cancel, List Box и т.п. Hо для такого случая, IMHO лучше VX-REXX не придумать.

Вот список функций, которые имеются в ydbautil:

Из RXU v1.a help:

Starting with this version of the RXU function package, all the pieces of the package will have the name RXU (no longer any references to YDBAUTIL).
