SYS)249

TRA     SYS)249
SOURCE-CONTROL-WORD-TYPE-SD

This MOVPAK subroutine converts from scientific decimal to floating point leaving the results in the AC. The SOURCE-CONTROL-WORD-TYPE-SD has the same form as described under SYS)248.

SYS)250

TSX     SYS)250, 4
TARGET-CONTROL-WORD-TYPE-ID     *Note 1.

This MOVPAK subroutine converts the floating point value in the AC to internal decimal and leaves the results in the AC or AC-MQ.

*Note 1 The form of the CONTROL-WORD-TYPE-ID is as follows:

  • Prefix — is the sign of the scale. = PZE for plus. = MZE for minus.
  • Address — = Scale applied to internal decimal value.
  • Decrement — = Numeric length of value.

SYS)251

TSX     SYS)251, 4
SOURCE-CONTROL-WORD-TYPE-ID

This MOVPAK subroutine converts the internal decimal value in the AC or AC-MQ to floating point leaving the results in the AC. The SOURCE-CONTROL-WORD-TYPE-ID has the same form as described under SYS)250.

SYS)252

TRA     SYS)252
SOURCE-CONTROL-WORD-TYPE-SD
TARGET-CONTROL-WORD-TYPE-SD

This MOVPAK subroutine moves a scientific decimal field to a scientific decimal field. The CONTROL-WORD-TYPE-SD for both source and target have the same form as described under SYS)248.

SYS)253

TRA     SYS)253
SOURCE-CONTROL-WORD-TYPE-SD
TARGET-CONTROL-WORD-TYPE-ID

This MOVPAK subroutine converts a scientific decimal field to internal decimal leaving the results in the AC or AC-MQ. CONTROL-WORD-TYPE-SD has the same format as described under SYS)248 and CONTROL-WORD-TYPE-ID has the same format as described under SYS)250.
