ibm midrange - How does GO TO control flow work in COBOL? -



ibm midrange - How does GO TO control flow work in COBOL? -

procedure partition mainpara display "hello main". go para1. display " sec display". stop run. para1. display " in para1". para2. display "i in para2" .... para200

i have little understanding of flow. but, confused. when command jump go para1, execute para1.

now question is:

will execute para2and homecoming mainpara? or execute para2 towards end of program?

i not cobol programmer, , need understand code migration tool/process, amxw cobol. target scheme ibm as/400.

go to statement permanently transfers execution 1 part of programme part of program. after go para1, execution jump para1 label, execute next paragraph , go on there.

output:

hello main in para1 in para2 . . in para200

so, execution continue until encounters stop run statement or runtime error.

note: go to statements considered bad practice reason. becomes harder maintain track of go to statements go speak. i'd suggest using perform instead. returns command after executing procedure.

assembly - What is the addressing mode for ld, add, and rjmp instructions? - hey guys know ldi (load immediate) addressing mode set immediate , st instruction addressing mode set index. however, have no thought others curious are! thanks :) the addressing modes explained in instruction set, in first few pages. in table of instructions see operands instruction determine addressing mode. mode indicated arguments assembly instruction. for example, ld had several different ways of operating, depending on arguments. 1 of them ld rd,x d number of register, such ld r3,x . ld r3,-z else (although both indirect addressing). rjmp k relative addressing, jumping pc + k + 1. add rr,rd direct register addressing. result contained in rd. assembly avr instructions
