A-Shell Consolidated Reference

Updated August 2022; see History

CALL <label>                                             ! traditional routine (GOSUB)

CALL <procedure>(<param list>)

CALL <function>(<param list>)

CALL DYNFUNC(<function>,<paramlist>)

The CALL statement may be used to call traditional BASIC subroutines, in which case it is equivalent to GOSUB, as well as to call structured Procedures and User-Defined Functions (including dynamically).

Examples

CALL HELP                              ! equivalent to GOSUB HELP

call Print'Cus'Addr'Label(CUSTNO, CH)  ! procedure

Call Fn'Status'Message$(code)          ! function

call DYNFUNC$(func$, code)        ! dynamic function

History

2022 August, A-Shell 6.5.1720: CALL can now be used to invoke a dynamic function.
