UPLOAD PC FILE Usage

The UPLOAD PC FILE statement is used to transfer data from a PC to a z/OS platform.

UPLOAD PC FILE Syntax Description

Operand Definition Table:

Operand				Possible Formats											Referencing Permitted	Dynamic Definition
`operand1`	S	A	G	A	U	N	P	I	F	B	D	T	L	C	yes	yes
`operand2`	S	A	G	A	U	N	P	I	F	B	D	T	L	C	yes	yes
`operand3`	S							I							yes	yes

Format C is not valid for Natural Connection.

Syntax Element Description:

Syntax Element	Description
`work-file-number`	Work File Number: The number of the work file to be used. This number must correspond to one of the work file numbers for the PC as defined to Natural.
`operand1-2`	Field Specification: With `operand1` and `operand2` you specify the fields to be uploaded from the PC. The fields may be database fields or user-defined variables.
`statement`	Statement(s) to be Executed: In place of `statement`, you must supply one or several suitable statements, depending on the situation. No I/O statement may be placed with the `UPLOAD PC FILE` processing.
`ONCE, SELECT, GIVING LENGTH` `RECORD`	Options: For a description of the `ONCE`, `SELECT`, `GIVING LENGTH` options, refer to the corresponding sections in the description of the `READ WORK FILE` statement. The `RECORD` option is not permitted for PC work files. It will be rejected at runtime. When uploading data: If you wish to define a filler, you must use a dummy variable instead of the standard filler notation.
`END-WORK (r)`	End of UPLOAD PC FILE Statement: In structured mode, the Natural reserved keyword `END-WORK` must be used to end the `UPLOAD PC FILE` statement. You can specify labels or line numbers with `END-WORK` in structured mode. In reporting mode, the Natural statement `LOOP` is used to end the `UPLOAD PC FILE` statement. You can specify labels or line numbers with `LOOP` in reporting mode.
`LOOP (r)`

UPLOAD PC FILE Example

The following program demonstrates the use of the UPLOAD PC FILE statement. The data is first uploaded from the PC and then processed on z/OS.

** Example 'PCUPEX1': UPLOAD PC FILE                                    
**                                                                      
** NOTE: Example requires that Natural Connection is installed.         
** CAUTION: Executing this example will modify the database records!
