Hi Douglas,

your are right - but you have to think in hexadecimal. 2 bytes in hex are like 0x0000 to 0xFFFF. So you have to convert the decimal values to hex:

1282 => 0x0502 => 0x05 / 0x02 => Line 5 Column 2
1290 => 0x050A => 0x05 / 0x0A => Line 5 Column 10

Well said.

The manual reference is somewhat obscure.

The text there reads: 'Character 2 Cursor location (line and position). Updated on input operations that are not subfile operations that return data to the program. For example, hex 0102 means line 1, position 2. Line 10, position 33 would be hex 0A21.'

One could also define the DS like this:
D INFDS DS
D row 370 370I 0
D col 371 371I 0

...and then test the row/column values in a way that's easier to compare vs the DDS for the desired field/area on the display file.
