Without meaning to bump into what might be off topic, SYSCALL is
actually a CLIST instruction - not a REXX one (unless it's a case of
"nous avons changé tout ça")
E.g.
HELP_SELECT: +
SELECT (&ZCMD)
WHEN (UP) DO
SET HPAN = &HPAN - 1
*SYSCALL* MAXV HPAN HELPTOP
ENDO
WHEN (DOWN) DO
SET HPAN = &HPAN + 1
*SYSCALL* MINV HPAN HELPBOT
ENDO
OTHERWISE
ENDO HELP_SELECT
ISPEXEC DISPLAY PANEL(HELPANL&HPAN)
ENDO
<...>
/*-------------------------------------------------------------------*/
/* SUB-PROCEDURE MINV */
/*-------------------------------------------------------------------*/
MINV: +
PROC 0 +
HPAN HELPBOT
CONTROL END(ENDO)
SYSREF +
HPAN HELPBOT
IF &STR(&HPAN) > &STR(&HELPBOT) THEN +
SET HPAN = &HELPBOT
ELSE
RETURN
ENDO MINV
/*-------------------------------------------------------------------*/
/* SUB-PROCEDURE MAXV */
/*-------------------------------------------------------------------*/
MAXV: +
PROC 0 +
HPAN HELPTOP
CONTROL END(ENDO)
SYSREF +
HPAN HELPTOP
IF &STR(&HPAN) < &STR(&HELPTOP) THEN +
SET HPAN = &HELPTOP
ELSE
RETURN
ENDO MAXV
<etc.>
