The term col represents a data location (column number) within the CL raw data area. It must be preceded by a dollar sign ($).

If a CARD CHARACTERS command is used then any number is valid up to the maximum number of characters specified.

If the CARD CHARACTERS command is not used, the last two digits must be between 01 and 80 inclusive. If the number is three or four digits, then the first one or two digits represent the card buffer number. If col is only one or two digits, then it is assumed that you are referring to buffer 0 ($1-80), unless a SELECT BUFFER command has been used. For example, $61 will refer to buffer 0 column 61 (not buffer 6 column 1). To refer to the latter, use $601.

Examples of col :

$1

$605

$1278

 

$695 (only if CARD CHARACTERS used)
