Four EREXXTry programs are in this archive. One has no extra functions, and the other three each have functions specific to the intended usage.

EREXXTRY.CMD is the standard edition.
EREXXTRYSQL.CMD has SQL enhancements - auto-check for SQL errors after SQLEXEC calls, convenient syntax for processing a SELECT statement, and more.
EREXXTRYWPS.CMD has WorkPlace Shell enhancements. These include applying a SysSetObjectData (WinSetObjectData in OS/2 C) setup string to a directory and all its subdirectories (great for AutoSort), querying an object's setup string (requires WPTools by Henk Kelder), searching an object handle based on title (also requires WPTools), and more.
EREXXTRYMATH.CMD is the largest, with 33 ready-to-use functions (plus support functions) for mathematical and scientific calculations. It is self-documenting - each function has two comments, the brief abstract and the full information. Functions are laid out like this: (some elements are optional)
FUNCTION_NAME: PROCEDURE /* FUNCTION: brief description of what function does */
[optional code here, eg PARSE ARG]
/*
Longer description
Parameters: list,of,parameters
where <longer descriptions of parameters>
Returns: description of return value
*/
