an example can be found on AMOSPro_Tutorial:Tutorials/Procedures_1.AMOS

Procedure NAME
: : :   Amos instructions go here
End Proc

You can also return a value from the procedure like so:

Endproc[number]
Endproc[real#]
Endproc[s$]

These values can be subsequently read by your program with PARAM, PARAM#, and PARAM$ respectively.
