VT52, VT100, and VT320 Sessions

There are special considerations for VT52, VT100, and VT320 sessions. The Ctrl+H key maps to an operation named DELTA (represented by the ASCII character D, which has a decimal value of 127), a nondestructive backspace. The syntax for sending the non-destructive backspace from a REXX program is @"DELTA".

The Backspace key maps to the BACK_SPACE operation, a destructive backspace. When specifying a destructive backspace from a REXX program, you need to suppress the Enter key. The syntax is:

'SESSCMD /@"BACK_SPACE"@"SEND"/ SESSION(sessname)'
