Using SALIAS15.REL SALIAS 1.5 is distributed in M-REL format so that it can easily be linked with new or experimental alias modules (and with new system library versions). The alias actually written to disk makes up the first few records of the program. In this case, it is Joe Wright's alias module from ALIAS 1.5. SLRNKP SALIAS/N,/A:100/J,ALIAS0,SALIAS,/E or ZML SALIAS=ALIAS0,SALIAS or LINK SALIAS=ALIAS0,SALIAS[NR] SALIAS contains a .REQUEST op for VLIB,Z3LIB,SYSLIB. By tradition, the alias module is expected to be 8 records in length or less. SALIAS and its installation program require only that the alias module end on a record boundary and be no more than a few kbytes in size. The current ALIAS0 is 7 records, so SALIAS proper begins at 480H. SAINST.COM reads the entire SALIAS program, looks for a signature string at SALIAS's installation table, then writes back your changes to that particular record. In other words, the alias module can change size and the installation program still works on the SALIAS you generate. Unfortunately, M-REL files cannot be installed directly. Any alias experimentation should be based on ALIAS0. SALIAS expects the general structure and public declarations you will find in this module. Thanks to Joe Wright for permission to combine his interesting new alias with the SALIAS editor.
