WEB READNEXT QUERYPARM

Description

WEB READNEXT QUERYPARM retrieves the next keyword parameter (name and value pair) in a query string in a URL.

The data is returned in its unescaped form (see Reserved and excluded characters for an explanation of this).

Options

QUERYPARM(data-area)

Specifies the buffer to contain the name of the keyword parameter being retrieved. The case of the name is as it is stored in the keyword parameter.

NAMELENGTH(data-area)

Specifies the length, as a fullword binary value, of the keyword parameter name. The actual length of the name is returned in this data area. If the length of the keyword parameter name is less than the size of the buffer, the keyword parameter name is placed in the leftmost byte positions.

VALUE(data-area)

Specifies the buffer to contain the value corresponding to the name returned in the QUERYPARM data area. CICS® unescapes any escaped characters before placing them in the buffer.

VALUELENGTH(data-area)

Specifies the length, as a fullword binary value, of the keyword parameter value. The actual length of the value is returned in this data area. If the value exceeds the buffer length, it is truncated. If the length of the keyword parameter value is less than the size of the buffer, the keyword parameter value is placed in the leftmost byte positions.
