SETMODE Procedure
The form of the SETMODE procedure is:
filenum input
INT:value
is the number returned by the OPEN call that opened the line. In a SETMODE call,
you supply this variable to EnvoyACP/XF.
function input
INT:value
is an integer value you use to specify the desired SETMODE function to
EnvoyACP/XF. Table 4-4
lists the SETMODE codes.
parameter-1 input
INT:value
is a subcode you use, along with the function value, to further define the desired
mode setting operation. Table 4-4 lists the SETMODE codes.
parameter-2 input
INT:value
is a subcode you use, along with the function value, to further define the desired
mode setting operation. Table 4-4
lists the SETMODE codes.
last-params output
INT:ref:2
is the name of a two-word integer array into which EnvoyACP/XF places the
previous values of parameter-1 and parameter-2 for the specified SETMODE
function. The format of the array is:
last-params[0] = parameter-1 value
last-params[1] = parameter-2 value (if applicable)
If the SETMODE call includes only function and last-params, the specified
function is not performed. Instead, EnvoyACP/XF fetches the most-recently used
values of parameter-1 and parameter-2 for the specified function and places
them into the last-params array.
CALL SETMODE ( filenum !i
, function !i
, parameter-1 !i
, parameter-2 !i
,[ last-params ] ); !o
