USAGE

.OPERATION: LI X [p11],[p12],[p13],[p14]

LI X11,X12,X13,X14

.INPUT FILE: PIC001
[Enter the file of interest.]

.ENTER X-COORDINATES (MAX 20): 3,6-8
[Enter one x-coordinate for each specified register.]

ENTER Y-COORDINATES (MAX 20): 7,12,1,33 [Enter one y-coordinate for each specified register.]

[If e.g. LI X [p11],[p12],[p13],[p14} has been entered, register variable [p11] will receive the image value found at (nsam=3,nrow=7), register variable [p12] will receive the image value found at (nsam=6,nrow=12), register variable [p13] will receive the image value found at (nsam=7,nrow=1), and register variable [p14] will receive the image value found at (nsam=8,nrow=33).]
