10 | * REXXAPI.C * |
||
11 | * * |
||
12 | * This program adds a ZIP engine directly to the REXX language. * |
||
13 | * The functions are: * |
||
14 | * UZDropFuncs -- Makes all functions in this package * |
||
15 | * unknown to REXX. * |
||
16 | * UZLoadFuncs -- Makes all functions in this package * |
||
17 | * known to REXX so REXX programs may * |
||
18 | * call them. * |
||
19 | * UZFileTree -- Searches for files matching a given * |
||
20 | * filespec, including files in * |
||
21 | * subdirectories. * |
||
22 | * UZUnZip -- Unzip command-line entry point. * |
||
23 | * This is functionally equivalent to * |
||
24 | * using Unzip as an external program. * |
||
25 | * UZUnZipToVar -- Unzip one file to a variable * |
||
26 | * UZUnZipToStem -- Unzip files to a variable array * |
||
27 | * UZVer -- Returns the Unzip version number * |
||
28 | * * |
