Appendix C: Conversion Charts

The following pages contain the EBCDIC-to-ASCII Character conversion chart. Characters under the “RECV” heading are the EBCDIC characters received from the SNA host. The ASCII equivalent is to the right under the “CONV” column. When EBCDIC data is directed to the printer the characters will be changed as described under the “PRT CONV” column.

The following notes are used to clarify the charts.

1.New Line - Send carriage return line feed (CRLF) to VDU.

2.Vertical Channel Select - Sends one line feed to printer and throws away next character.

3.Horizontal Tab - Positions print head by using spaces to correct column to page if tabs setup by SHF command.

4.Vertical Tab - Positions page by using CRLFs to correct line if tabs setup by SVF command.

5.Form Feed - Sends form feed character, or number of CRLFs if option set to position paper to top of page.

6.Throws away this character and two following if printer selected for a LU Type 3 running in Interactive mode(cursor positioning).

7.Sends CRLF to printer, checking for bottom of page and if so, positions paper to top of form by using additional CRLFs or sending a form feed.

8.Sends Backspace to printer if printhead positioned to column 2 or greater.

9.Sends LF to printer, checking for bottom of page and if so, positions paper to top of form by using CRLFs or the form feed character.

10.Indicates start of SNA character string (SCS), characters following will be handled as described in Section 8.3 (SHF, SVF, SLD and VCS command).
