Below is a table listing the subroutines (aka xcalls) found in A-Shell. For general information about subroutines, see the following Introduction topic.
This table alphabetically lists A-Shell’s most generally useful routines. Most of these routines are embedded in A-Shell, but some are written in BASIC and are provided as separate files. In the "Origin" column abbreviations are used for Alpha Accounting ("AA"), Alpha Accounting UK ("AA UK") and MicroSabio ("MS").
Follow the links to the individual pages providing details about the routines.
