If the error message:
is returned after the BEGPLOT or ENDPLOT commands have been invoked, the reason is that another application package or ICL procedure has switched parameter checking on within ICL (SG/5). The problem is simply overcome by typing the command:TOOFEWPARS Not enough procedure parameters
The PONGO commands will then work correctly.ICL> set nocheckpars
