IT
Transfers a tape record to the primary input buffer.
Syntax
IT{C}{A}
Syntax Elements
C performs an EBCDIC to ASCII conversion of the data prior to placing it in the buffer.
A masks 8-bit ASCII characters to 7 bits (where the most significant bit is 0).
Operation
IT reads a tape record (with a maximum size of 300 bytes) into the primary input buffer, starting at the beginning of the buffer and destroying the current buffer contents.
The pointer is positioned at the beginning of the buffer after an IT command is executed. The data is read from the tape exactly as it appears.
IT does not convert blanks to attribute marks.
