Abstract

ooRexx makes it very easy to define public routines and public classes stored in a single file (package). This presentation introduces a set of useful public routines and public classes that are designed to ease manipulating strings. All string related BIFs (built-in-functions) are enhanced such, that it becomes possible to carry out operations in caseless mode (by default) that are otherwise case-dependent, like ABBREV(...), CHANGESTR(...), COMPARE(), COUNTSTR(...), LASTPOS(...), POS(...) or WORDPOS(...). In addition negative position and length parameters become possible, which may be known from other programming languages, e.g. WORD2(string,-2) will extract the second to last word from the given string, SUBWORD2(string,-1,-2) the last two words from the given string. In addition the class "StringOfWords" allows for defining words assembled from non-English characters (like German umlauts), offering all of the word-BIF related functionality in form of respective methods, that also allow for negative position and length values. Finally, this utility package defines a few comparison classes for sorting and supplies a public routine that eases its usages for sorting for the Rexx programmer. The package works for ooRexx 3.2 and was tested under the alpha version of ooRexx 4.0.
