2 * REXXAPI.C *
3 * *
4 * This program adds a ZIP engine directly to the REXX language. *
5 * The functions are: *
6 * UZDropFuncs -- Makes all functions in this package *
7 * unknown to REXX. *
8 * UZLoadFuncs -- Makes all functions in this package *
9 * known to REXX so REXX programs may *
10 * call them. *
11 * UZFileTree -- Searches for files matching a given *
12 * filespec, including files in *
13 * subdirectories. *
14 * UZUnZip -- Unzip command-line entry point. *
15 * This is functionally equivalent to *
16 * using Unzip as an external program. *
17 * UZUnZipToVar -- Unzip one file to a variable *
18 * UZUnZipToStem -- Unzip files to a variable array *
19 * UZVer -- Returns the Unzip version number *
20 * *
