[Coco] Assembly Code from within a C program.

[coco at jechar.ca]

Thanks replaceing strlen with strlength eliminated the original errors
but it appears that the os9 directive in the assembly code is not
supported by CMOC as my results are now.

cmoc --os9 hi09a.c
hi09a.s(75) : ERROR : Undefined symbol I$WritLn
hi09a.s:00075  os9 I$WritLn

hi09a.s(79) : ERROR : Undefined symbol F$Exit
hi09a.s:00079  os9 F$Exit

So rather then pursue this further I would like to know how to write
an assembly program that takes parameters directly from the os.

For example a program HAYU that works like this

{Term | 02 }/DD:hayu
Hello ?

{Term | 02 }/DD:
{Term | 02 }/DD:hayu Pierre
Hello Pierre.

{Term | 02 }/DD:hayu Charlie
Hello Charlie.
