SSNULL Procedure

SSNULL initializes extensible structured token structure with null values.

SSPUT and SSPUTTKN Procedures

These procedures insert tokens into an SPI buffer (previously initialized by SSINIT) or

perform operations on the buffer. (Do not use SSPUTTKN in COBOL programs.)

server-

version

value Version of subsystem or server program

checksum value Checksum flag (enables or disables checksum protection)

max-field-

version

value Unsigned integer value that initializes maximum field

version of buffer header (default = 0)

SSNULL ( token-map ! i

, struct ! o

[ , constants ] ) ! i

Parameter Value/Ref Description

token-

map

ref:* Token map to use to initialize fields in structure

struct ref:* Structure to be initialized with null values

constant ref:1 Pointer to constant values returned by XSTACKTEST procedure

SSPUT ( buffer ! i,o

SSPUTTKN , token-id ! i

, [ token-value ] ! i

, [ count ] ! i

, [ ssid ] ) ! i

Parameter Value/Ref Description

buffer ref:* SPI buffer into which tokens are placed

token-id ref:* (SSPUT)

value (SSPUTTKN)

Token code or (for SSPUT only) token map of token or

special operation

token-

value

ref:* Value of token-id

count value Number of elements in token-value (default = 1)

ssid ref:6 Subsystem ID (default = SSID in header or current list)
