upload problem

i had a strange problem today
i was trying to upload a program from an s7 314 cpu (one with flash eprom not the new ones) and i found this block with some compilation error and timestamp errors , the amazing thing is that the sequencce is running ok and iam wondering why

this is a part of the program

BLD 103
A M 3.1
= L 40.7
BLD 103
Call
BLD 1
= L 41.0
L 4688

End Call
NOP 0



the call and end call statements are marked in red

when i removed these statements i was able to download the program to another cpu but the sequence did not work in the same manner


can anyone explain what is going on
by the way what bld mean?




The call and end call are marked i red

any answere for that?

i need help..

hi
i never see "end call" instruction.

and in "call" function you need to put an argument

i will follow if someone solve this strange queto.
