Use with READ
In Read file statements, the optional "POS=num-expr" clause is used only with external files opened for RELATIVE processing; its purpose is to position to a specified byte before reading. After the numeric expression (usually a simple numeric variable or constant) is evaluated and rounded to an integer, the system reads a complete record beginning at the specified byte number. If "POS = num-expr" is not specified, the system sequentially reads the next complete record after the last byte read.
Use with FORM
In FORM statements, the POS parameter refers to a position on the screen by column. POS is followed by a space and then any integer or numeric variable. The following example will print the name "Camilla" starting at column 60:
00100 Print using nameform: "Camilla" 00110 nameform: form pos 60, c 15
POS is also used while printing to a printer or window.
