1.1 Variables
Example:
Program code
DEF INT state=0
DEF REAL resultR=0
DEF FRAME resultF=0
IF (GETVARTYP("$MA_MAX_AX_VELO") <> 4) GOTOF error
state=GETVARDFT("$MA_MAX_AX_VELO", resultR, AXTOINT(X))
IF (result < 0) GOTOF error
IF (GETVARTYP("$TC_TP8") <> 3) GOTOF error
state=GETVARDFT("$TC_TP8", resultR)
IF (GETVARTYP("$P_UBFR") <> 7) GOTOF error
state=GETVARDFT("$P_UBFR", resultF )
Read data type
Syntax:
