[comp.lang.forth] F83 Assembler help

sms@sugar.hackercorp.com (Stanley M. Sutton) (03/02/90)

Could someone direct me to a tutorial publication to assembley in
F83.  The main area I need help in is conditionals.  I'm not sure
of how I go about coding things like JNZ in F83 assembly.

	You might check back issues of FORTH Dimensions Magazine.

	Examine the KERNEL86.BLK source for examples of usage.

	If I recall correctly, all the jumps and calls take syntax
like:

	MY-LABEL #) JMP MY-LABEL #) JNZ MY-LABEL #) CALL
	MY-LABEL MY-SEG #) FAR CALL

	Try various combinations of such until the machine
ceases to crah ... :-)
