For example, the following program uses the files RBOOT and RLOAD under the ProDOS enviroment to load a relocatable routine file READBITS.0, file type REL, 87 bytes long:
10 AD=0
20 PRINT CHR$(4);"BRUN RBOOT"
30 AD=USR(0),"READBITS.0"
However, when the program runs, the error "No Buffers Available / Break in 30" occurs under BASIC.SYSTEM version 1.1, ProDOS version 1.1.1, and ProDOS EdAsm, release 1.0 dated 15-JAN-84.
To workaround the problem, insert: DS 1024,$EA
at the end of the program.
