DEXEC 3 (Remote I/O Control)

DEXEC request code 3 performs remote I/O control operations such as backspace, write endoffile, and rewind.

DEXEC(dest,code,cnwd][,p1[,p2][,p3][,p4][,0,0,keywd])

dest

16-bit integer. The Router/1000 node address of the

 

node where the call is executed. A value of -1 indicates the

 

local node. Local execution will also be performed whenever

 

dest equals the local node address.

code

16-bit integer. I/O control request code = 3.

cnwd

Control word. (See the RTEA Programmer's Reference Manual

 

for an explanation of this parameter.)

p1,...,p4

Required for list output line spacing and various other

(input/output)

functions. (See the RTEA Programmer's Reference Manual for

 

details of the contents of these parameters.)

0,0

Formal place holders that must be included whenever keywd is

 

specified.

keywd

The locked LU's keyword number.

 

 

Note

DEXEC 3 calls to HPIB devices that do double buffering are

 

not supported. Use PTOP to implement I/O control operations

 

to HPIB devices.
