# stdglue - canned prolog and epilog functions for the remappable builtin codes (T,M6,M61,S,F)
#
# we dont use argspec to avoid the generic error message of the argspec prolog and give more
# concise ones here
# cycle_prolog,cycle_epilog: generic code-independent support glue for oword sub cycles
#
# these are provided as starting point - for more concise error message you would better
# write a prolog specific for the code
#
# Usage:
#REMAP=G84.3 modalgroup=1 argspec=xyzqp prolog=cycle_prolog ngc=g843 epilog=cycle_epilog
