Unfortunately classical mainframe has no builtin decompressing software for ZIP files. What you could do: Transfer ZIP file to USS, decompress and unpack there, then copy back to MVS. To do it directly on MVS you need to purchase a separate utility to do this. One utility is FLAM, Frankenstein Limes Access Method. FLAM is a product of limes datentechnik.
Given a ZIP file which contains 10 files.

See 1027: Need example to unzip ZIP file with multiple files in it.
Three things are noteworthy:
- All members of ZIP archive are processed via
/?* - Output files are dynamically created using
[AX-BY], then using first 7 characters, adding first character from extension - Target CCSID is specified
From FLCLBOOK.txt:
This is the list of supported processing rules:
- [path] - Extracts the string before the last slash or backslash, i.e. the path without trailing (back)slash
- [name] - Extracts the part after the last (back)slash, i.e. the filename
- [base] - Extracts the part between the last (back)slash and the last dot, i.e. the filename without extension
- [ext] - Extracts the part after the last dot, i.e. the file extension
- [member] - Extracts a string enclosed in round brackets from the filename part of the string, e.g. a PDS member name on z/OS
- [copy] - Simply copies the input string (useful if you only want to add an extension)
- [upper] - Converts all characters to upper case
- [lower] - Converts all characters to lower case
- [title] - Converts the first character to upper case, all others to lower case
- [cutX] - Cuts off the string after the X-th character, where X is a positive or negative number indicating how many characters to keep, counting from the front (positive) or back (negative)
- [indN] - Inserts the current index as decimal number of at least length N (padded with preceding zeros) N is any number between 0 and 9, where 0 results in variable length numbers with their shortest possible representation (no preceding zeros)
- [rndN] - Inserts random numbers of length N (with preceding zeros) N is any number between 0 and 9, where 0 results in variable length numbers (no preceding zeros)
- [AX] - A is a place holder for a single-byte character, X is a positive or negative number; Extracts the string part between the X-th occurrence of the specified character and the next occurrence of that same character. If X is negative, search starts at the back and in reverse. If X is 0, the part before the first occurrence of A is extracted.
- [AX-] - A is a placeholder for a single-byte character, X is a positive or negative number; Extracts the string part after the X-th occurrence of the specified character. If X is negative, search starts at the back and in reverse. If X is 0, the input string is copied.
- [AX-BY] - A and B are placeholders for a single-byte character, X and Y are positive or negative numbers; Extracts the string part between the X-th occurrence of A and (relative to that occurrence) the Y-th occurrence of B. Like above, negative numbers mean counting from the back.
- [search=replace] - Replaces the first occurrence of the string 'search' with the string 'replace'
- [search=*replace] - Replaces all occurrences of the string 'search' with the string 'replace'
- [table] - Evaluates to the current table name if end of table handling is activated (only when reading tables)
